Basil

Basil (Ocimum spp.) has its roots in India and Africa but is mostly known and appreciated all over the world. The word basil comes from Greek basileus meaning King and it certainly can be considered royalty among herbs.

Care
Basil has broad, dark green aromatic leaves that can be grown from seed. It should be started indoors in early spring (May) or sown directly in the garden after danger of frost has passed. Basil needs warm soil and temperature to germinate. If started too early you will get slow, weak growth so don’t rush it. Transplants can be planted when temperatures are above 50 degrees at night. This heat loving annual, thrives in warm weather, requires full sun and a rich well drained soil. As with many herbs, it needs little fertilizer; in fact with too much fertilizer, basil will develop a bland flavor. Container grown basil will need more water and fertilizer than basil grown in the ground.
Plant 12 inches apart to allow room for growth as they grow as wide as they get tall (12-24 inch). To maintain the size and shape of this vigorous growing plant, pinch frequently.  For best leaf production and flavor harvest basil often.

Flowerheads and Pruning
Once the plant reaches maturity or temps are over 80 degrees, look for emerging flower heads which will drain the plant of energy to produce more leaves. Pinching or deadheading doesn’t stop flowering, it encourages more flowers.

To discourage flower production and stimulate more leaf growth, cut the stem at least six leaf nodes down or leave 2 sets of healthy leaves from the bottom of the plant. Depending on how quickly the plant grows, you may have to prune once a month. If basil is allowed to go to seed, the leaves will develop a bitter flavor. For a continuous supply of fresh basil, plant at three week intervals during the summer. Plant basil next to tomato plant to improve their flavor.

There are more than 150 species of basil grown around the world. Even the most popular have a wide range of leaf shapes and flavors from anise, camphor, cinnamon to lemon. Sweet Italian Basil has an anise flavor which brings out the essence of summer tomatoes. ‘Genovese’ as well as bush basil (O. basilicum minimum) are great for pesto and Thai (Siam Queen) impart a spicy flavor with a hint of licorice to Thai and Indian cuisine. The dwarf to medium sized basils; such as Little-leaf bush or Spicy globe are ideal for small pots and window boxes.  Dark Opal Basil stands up as a culinary herb but also works well as a decorative accent plant.
Combine basils with parsley, sage, rosemary and chives along with any one of your favorite herbs in a large container, place it close to the kitchen door and you will have a convenient culinary herb garden at your disposal.

Basil tip: Mosquitos and flies dislike the smell of basil. Grow it on a patio or deck to keep them away.
Rub crushed basil on your skin to repel mosquitoes.

Problems; light green/yellowing leaves possible overwatering or needs fertilizer. Black dying leaves-cold weather
Insects:  Aphids, Japanese beetles, slugs feed on the leaves.
Disease:  Damping-Off (Rhizoctonia), root rot and fusarium wilt and leaf spot

    BASIL LEAVES ARE SMALL AND SPOTTED. PLEASE ADVISE

    Are they growing in a container or outdoors? Are the leaves smaller than before or is this a small leaved variety? There are several bacterial diseases that will affect basil causing gray-black water soaked spots on the leaf. Remove the spotted leaves and keep them as dry (no water on the leaves). Water the soil only to prevent the bacteria from splashing back on the leaves.

    Pinching off the blooms
    I am growing Basil and did not know to pinch the blooms. Will it hurt the plant? If I start now will it help. The leaves are small.

    Thanks!

    Before basil starts to bloom pinch off the entire flower stalk and then some. It’s better to pinch further down the stem, this will delay the plant from producing more flower heads. It will not hurt the plant, in fact it will make the plant send out lateral growth and make it fuller. There are varieties of basil that have small leaves. It’s best to pinch off the flower head before it starts to show. If you allow it to go to seed, then basil leaves become bitter.

    Propagate Basil
    How can I propagate basil. I have a large plant in the garden and would like to save it for the winter indoors.

    Basil can easily be propagated by taking cutting from the mother plant. Choose fresh growth tips, remove any flowerheads and place the cutting in water. It should root within a week. Plant the rooted cutting in well drained potting soil. The other option is to dig the basil up before the frost hits and keep it indoors. Because of lower light conditions indoors, basil may not survive the whole winter season but should last for a few months.

    Am growing basil outdoors in a pot – sunny spot, gets lots of water. Is starting to wilt and leaves turning slightly yellow. Too much water? Too much sun?

    Most likely, too much water. Let it dry out between waterings. Be sure that the water drains out from the bottom and the pot is not sitting in water. Basil loves sun but if the roots are stressed out it will wilt so move it to a slightly shaded spot until it recuperates. It may also need a dose of fertilizer, once the plant perks up.

    Leaf spots
    I am watering soil only. It is strange that all of the spots are the same even though on different plants. Note – The light shaded web shape is shiny.

    Hi Robin
    Does it look like a tannish gray star with a black spot in the center, then the black center blisters and looks shiny and moist?
    Leaf spots are caused by bacteria or fungi. If the spots are shiny with no spores on the surface, then it is most likely a bacteria. Bacteria spots often produce a light halo with a dark spot in the center. If you see spores then it is a fungal infection and a fungicide will work.
    Seeing that this is an edible herb, I would go the simplest route and that is to avoid any rainfall or getting the leaves wet (that’s how it spreads). Warm humid weather, dew, condensation also help spread the infection. Hope this helps.

    I am growing Italian basil and the plant grew beautifully until the roots got hard and woody looking. Is this normal? What can I do to prevent? Thanks.

    Are you growing the basil in a container? When the roots get too crowded in a container,with little soil and stressed, then it starts to mature faster, produce woody stems, roots and flower heads. Remove the flower heads as soon as they start to show and pinch the top of the plant to get a bushier plant and more growth.

    Pinching basil
    My basil plants grew- from seed- and I’m very excited to have it. I live in a cold northwestern climate and planted them in a container that I keep in my kitchen window. They’re doing so well I’m afraid to touch them. I’d like to use it this summer for cooking, but don’t know how to clip leaves without hurting the plant. I read something about clipping a quarter inch above the “node” but I’m not sure where that is and if there’s more than one- where do I start? Until I read this I didn’t even know it could flower. Do I start at the top, the bottom or the side of the plant and where do I clip?
    Thanks for the help.

    HI Carrie
    Basil is a really easy plant to pinch back. A node is where new growth starts, its the “bump” in the stem where the leaves come out. Basil can get leggy and pinching them will make them bushier (fuller) thereby giving more leaves to use. Start from the top, pinch off up 1/4 inch above a node. New growth will them come as side shoots from the node. Don’t pinch until you have at least 3-4 nodes on the stem or the plant . The larger the plant the more you can cut off. Hope this helps. Basil is great in pasta sauce and of course pesto. Enjoy!!

    Slugs
    My basil plants are out in my veggie garden, seperate from the other plants and there seems to be some sort of bug eating at the leaves at night what can I do?

    Hi Kelly
    It seems many insects like the taste of basil. It’s possible that slugs could be feeding on your basil at night. I’m having problems with Japanese beetles chewing on the leaves during the sunny part of the day. Plant basil in a pot and grow it on the deck that you can look out for insects.

    My basil is in a plastic container, the problem is the the bottom of the stalk is getting brownish and the leaf is starting to wilt. I already give it a lot of water.This is the third time my basil tree has the same problem. what should i do?

    Hi Ronnie
    You may be giving it too much water. Keeping it too wet can cause root and stem rot. Let the plant dry out between waterings. Make sure the excess water drains from the bottom of the pot and don’t let it sit in water.
    A brown stem can be normal, as basil develops a woody stem at the base when it matures.

    Cutting back basil
    I have 3 basil plants growing in a planter. They have been growing like crazy all summer and I have been careful to pinch off the tops before any flowers appear. I had 1 flower pop up on 1 of the plants and now all 3 plants have a strong licorice/bitter flavor. Is there any way to recover the sweet flavor? What are my options?

    Hi Rachael
    Before basil starts to mature(flower), cut it back up to a node that has fresh shoots or up to 6-8 inches from the ground. It will send out new tender growth. If a flower stalk develops, its almost too late to avoid the bitter taste. Another option is to take a non-flowering tip cutting and start a new plant. For a continued supply of sweet basil, some gardeners will plant it every 2 -3 weeks.

    I am growing some Ocimum gratissimum in the UK from seeds I picked in Nigeria. I have a number of small plants growing which I am keeping in plastic “tents” to try and replicate the humid climate. They seem to be doing ok, however recently the leaves on the plants have started turning yellow in between the veins, which remain green. Any suggestions?

    Hi Olly
    If the new growth is showing these symptoms, then there’s a chance that the leaves are chlorotic and may need more iron or manganese. If lower leaves have interveinal yellowing then lack of magnesium may be the problem. A dose of a balanced fertilizer with micronutrients may improve the situation.

    Puckered, wrinkled leaves
    Basil: I have plants in my garden that look healthy except the leaves started to wrinkle instead of open to be smooth. What can I do?

    Hi Bill
    There’s nothing you can do. When basil is in its juvenile stage it will grow smooth leaves, as it matures the leaves become puckered or wrinkled which is one of its characteristics.

    I just got my first Basil plant and it’s in a plastic pot. I keep it in a sunny place and water it on days that it does not rain. However most of the plant has died away just leaving brown stalks, and the leaves that are left are brown spotted. I don’t want to toss the pour thing but I don’t know how to save it.

    Hi Virginia
    It doesn’t sound like your basil plant can be saved. If all that is left is brown stems and spotted leaves then it may be that the plant is diseased and needs to be tossed. If there is any healthy growing tip on the plant take a cutting and root it in water for a new plant. You can try to cut back the plant and see if it sends out some new growth.

    The brown spots are most likely some type of leaf spot caused by a bacteria or fungus. I would cut them out and hope you get some healthy new leaves to eat.

    Spindly growth
    Hi, my Sweet Basil plants are growing quite nicely except the stems seem to be very weak. Is this normal? If not, what do I do about it?
    The plants are growing in a pot outside on a sunny balcony.
    Thanks!

    Hi Ming
    There are a number of reasons why basil will produce weak, spindly growth. It may not be getting enough sun or nutrients (fertilizer). Pinch or cut the plant back to encourage bushier growth and stronger stems.

    Frozen Basil

    Can you do anything with a basil plant after it has been affected by a frost ? Can you still use the basil ?

    Hi Mary Ann
    Once basil is “frozen” it will turn black and not worth using. If it was only slightly affected by cold temperatures, then trim the blackend leaves, bring it indoors and hope that it will send out new growth otherwise toss it.

    I have tried Basil as a house plant many times but it never seems to live. It always seems to get infected with bugs. Then the rest of my plants get the bugs. Can basil live as a house plant with other house plants? If so what can I spray it with to kill the bugs and and still use the basil for cooking?

    Hi Ariel
    Basil is a difficult plant to grow indoors during the winter. It needs lots of sun, warm temps and humidity to thrive. The only safe way to remove bugs is to pick or wash them off with water and then you can eat the leaves.

    I live in North Florida. I planted Basil in Summer. It grew fine than stopped, turned yellow and has not really done anything. Will it grow now that the weather is cooling a bit or just die off. I’m not sure if I should just pitch it or maybe move it to a bigger container? Ahhhh…It’s in a 4″.

    Hi Tracy
    You can try to cut it back and repot in a larger 6″ container. See what happens. It likes lots of sun and warm temperatures to grow well. Have you fertilized it lately?

    Preserving/freezing basil
    My basil plants is dropping all it’s leave since I brought it indoors for the winter. I live NE of Philadelphia. It sits near my sliding glass door. Help. I don’t want to loose the plant. I use it for many recipes. Can I dry the leaves or freeze them? How?

    Hi Sandy
    Basil doesn’t grow well indoors in winter unless you have plenty of light and warm, humid temperatures.They tend to slow down and get leggy in the fall when the days get shorter. If you pinch it back, it may send out a few new leaves but that won’t last long. A grow light might help. I had great basil all winter when I grew it in my Aerogarden.
    Unfortunately, basil does not freeze or dry very well but you can do it. The best flavor comes from the oils in the leaves which are lost when basil is dried so freezing would be the better option.
    Freezing the leaves will turn them black but you can freeze them in ice cube trays to make herb cubes. Chopped basil leaves can be frozen in water or oil. Here’s one way: Pour olive oil into an ice cube tray about 1/4 full, chiffonade the leaves and push into them into the oil and freeze. Once frozen add more oil on top and freeze. Once frozen remove the cubes and put them in a freezer bag. It’s great to add to soups sauces. You can also make pesto which is great with pasta.

    Too much water can cause the leaf tips to brown. Let the plant dry out between waterings and make sure the plant doesn’t sit in water.

    Hello, my poor basil plant needs some help. The stock and the stems are brown and very brittle, with No actual basil leaves on them. I went away for 5 weeks on holiday and returned to this. I had a friend water it during this time but no help.

    Is it time to say good bye to this plant? I have had it for over 3 years. Or can I salvage it somehow.
    Thanks

    Hi Susan
    Yes, its time to say goodbye. Great job on growing it for 3 years! Your basil may have succumbed to overwatering, root rot or other diseases that will attack it when in a weakened state. You can try to knock the plant out of the pot and inspect the roots. If they are a creamy white color then the roots are fine. In that case, I would trim off all the browned stems past the green healthy stem and see if any new growth sprouts.

    Hi Jessica
    Basil grows best in warm temperatures and full sun. Keep it in the sunniest window you have and as soon as it warms up (night temperatures 50F) in cold Berlin place it outside on the balcony. The warm sun will perk it up and encourage new growth. Pinch it back if the stems get too leggy to encourage bushier growth.

    Damping-off disease
    Hello,
    I am growing 3 small basil plants from seedlings on my balcony in Louisiana. Two of my plants in the last two days now have about a 1 inch brown section in the middle of the stem, and have flopped over, like someone chopped them in half. There are also small black gnat-like insects hanging around. I can’t seem to find what they are, or what to do about my felled stems. I’d like to use organic methods if i can save my plants. Please help!

    Hi Leanne
    It sounds like your basil plants have damping-off disease. Several different fungi can cause this disease but the symptoms are very similar. The lower stems of young transplants will have black/brown lesions, parts of the stem will turn soft and slimy. This watery soft rot can occur at or above the soil line. The end result is that it destroys new plants. There is no cure for the disease just preventative measures. Because you have fungus gnats, I suspect that you keep your soil too wet or that it is too dense and doesn’t drain well which can contribute to damping-off disease. Take out the healthy basil plant and replant in sterile, well-drained soil and provide good air circulation so the plant will dry out faster. The other two cannot be saved.

    HI Jessica
    Basil can get leaf spots which are caused by either a fungus or bacteria. If you plant has powdery mildew the spots are not as cleary defined-more of a white dusting in areas. If you have powdery mildew try spraying with a baking soda solution. Because you may want to use it for cooking use vegetable oil instead of horticultural oil in the mix. It will not elliminate but help control the disease

    I have basil plant potted with some cilantro and parsely. It looks droopy and one of the stems near the soil line is brown. It has been a chilly spring here – just now getting into the 70’s during the day. I have been bringing the pot indoors at night when temps drop below 50. I’m not sure what is causing the droop and brown stem…it gets decent sun and I keep it watered. Could it be the chilly weather or do you think I should take the basil out and give it its own pot? The cilantro and parsely are thriving and are much larger.

    Hi Rose
    Cilantro and parsley tolerate cooler temperatures than basil. Being crowded in the same container can also make it susceptible to fungal infections (stem is brown at soil line).

    Hi Melissa,
    It’s time to get a new plant. It’s the start of a loosing battle. Once it starts to bloom, the leaves will become bitter and tough. If you have some top growth that is not blooming, take a cutting and root it for a new plant.

    Hi! We have grown basil from seed, and currently have about 7 stalks in a pot. Ours are also flowering, which was when i starting to see what to do next. Only 2 or 3 have flowered, but they are still producing new small leaves on the bottom of the stalks. Should I cut down the plant to those new leaves or just below the flower? We also have in the same pot some flat leaf parsley from seed that is not thriving; any tips on those little guys? Any advice would help!

    Hi Lydia
    I would cut back the basil to the new small leaves and give it a light dose of fertilizer to get it going. Once the basil starts to flower, it will want to continue to do so. It will produce less leaves that are not as tasty. I would take some cuttings and try to root new plants-so you have continued basil for the whole season. I don’t know what is going on with the parsley. It does not transplant well. Could it be too crowded in the pot?

    Hi! Great website, loads of information here.

    Unfortunately, I am also having a small issue with two of my basil plants. They appear to be thriving and healthy, except for a small patch in the center of each plant where one or two stems are turning brown and withering away. It looks like white mold/watery soft rot from what I can find about it on the internet.
    Is there any way to treat this without losing the plant? Is the basil still safe to eat? Thanks in advance!

    Hi Alex
    Once it starts to turn brown there is nothing you can do. You may have some root rot or Fusarium wilt which causes sudden wilt caused by high humidity and poor air circulation. Remove the diseased stems so that it doesn’t spread to the rest of the plants.

    I noticed flowers on my Basil plant and started pinching them, but as you imply will happen, they just kept coming back. Finally, I read that I need to cut down the stalk to a lower node (wish I had come across this webpage earlier!). My question is, will the new growth leaves taste bitter, or will they be normal? In other words, is it too late to save this plant and will I have to replace it? Thanks!

    Hi Matt
    The leaf quality isn’t quite as good once they initiate bloom. They won’t be as sweet and tender tasting as the new leaves were but are still good. Once they start bloom, it seems that’s all the plant wants to do-so you can stave off blooming for a while and still get leaves but it will continue to try to bloom. I would start another one, to keep continued tender basil for the rest of summer.

    I grew my basil plant from seed in march. It started out indoors and was doing great. Then I moved it outside once it got really warm and it stopped growing. Not only that but it started to turn yellow. Then I saw flowers start to bud and I pinched them off. Now the stem is turning brown and woody and the leaves are going brown too. I don’t know what to do. I expectd them to grow bigger but they are about 6″ tall and it’s just one steam with no branches. I’ve tried watering it and then letting it dry out before watering it again. I checked for root rot and they are still white but really near the surface. Help, I don’t know what i’m doing. Can they be saved?

    Hi Karen
    Have you fertilized the plant? Make sure when you water that it flows from the bottom of the container so that the roots are encouraged to grow deeper. At this point there’s still time start over with a new plant.

    Scale?
    I just got a spicy globe basil plant that I am growing in a pot in my sun room. I have noticed that it is getting brown spots on the leaves and brown streaks on some of the stems. Also, some of the stems and brown streaks have very small round things attached to them that don’t come off easily. Otherwise the plant looks healthy. Any idea what is going on and how I can save it? Thanks so much!

    Hi Kristina
    The little brown round things are scale an insect that will be difficult to get rid of. The safest way (since you may be eating the leaves) is to remove them is to scrape them off and then wash the leaves. You can also dab them with a q-tip dipped in alcohol. The brown spots can be a sign of fungal or bacterial leaf spots. Try not to get the leaves wet and allow more air circulation around the plant. In the meantime, take a tip cutting and root it for a new plant.

    Hi Delaine
    Can you put it outside? that would be the best thing you can do. Trim some of the top growth back and give it a light dose of fertilizer-(not too much) to stimulate new growth. Water enough so that it runs out of the bottom on the container and then wait until the top 1-2″soil dries befire watering again.

As I was doing this I noticed the leaves began to develop large black patches all over the leaves that five minutes ago were bright green. What happened?

    Hi Beth
    Basil bruises very easily and starts to oxidize(turn black) when cut or bruised. One trick is to coat the basil leaves in oil. Washing them under running water most likely bruised the basil leaves.

    Leaf margin burnThis is so helpful! I got a potted basil that has delicious, spicy tiny leaves and everyday it seems like some of the leaves just instantly turn half brown. The stems look fine but the leaves turn brown from the outside in so fast. Am I watering too much? Not enough?

    HI Katie
    Brown leaf margins can be a sign of stress. You may be overwatering. Is the soil well drained or does the water sit on the surface and take time to drain? The other problem may be overfertilizing. Too much salt accumulation builds up in the soil and the plant can’t use it up fast enough. If so, leach out the salts by thouroughly watering letting the water run out of the bottom on the pot and then do it again.

    I have noticed lots of black ants crawling on and living on my basil plants. Is this good or bad ?

    Hi Scott
    I would look for aphids. Ants are attracted to the honeydew (clear sticky stuff on the leaves) that they produce.

    When I first got my basil plant it was about a foot tall and it was growing very well. I pinched the leaves and flowers in order to stimulate bushier growth. However, lately the plant does not seem to be growing. It’s not growing upward or outward it seems. In addition the bottom 1 inch of the plant is brown and getting hard like a twig, but only that portion. Also, every once and a while one of the leaves will just completely shrivel up and die. Lastly, the leaves are a little yellowish. What can I do to improve my plant’s health?

    Hi Ashley
    You can try to fertilize your basil plant and see if that helps. It is an annual and is in a mature stage of growth so instead of making tender new leaves it is focused on making flowers and seeds (even when you cut off the flower heads).

    I apparently overdried some basil hanging upside down in my garage, and most of it turned brown and brittle. This might be a dumb question, but I’m new to drying herbs… Are they still ok to keep and use in recipes? I know green and dry is preferable, but can you still use the brown stuff?

    Hi Julia
    There’s never a dumb question. Basil, more than other herbs will discolor when dried and loose some flavor but is still good to use in cooking. It won’t have the flavor like fresh basil. Another method of drying is in the microwave. I haven’t tried this but here goes.
    Start with a single layer cover with paper towel and cook on high for a minute. The leaves should be crispy. You will have to experiment with the timing so that you don’t over cook them. Store the dried leaves in an airtight jar away from light. Another way is to freeze pureed leaves in ice cube trays and then store them in plastic bags in the freezer.

    I just noticed a thin layer of webs, with teeny tiny white bugs, across the top leaves of my Indian basil. I placed the entire pot under a warm shower and then washed the leaves with a orange based dish detergent. I haven’t washed the leaves again, and was wondering if there is anything else I should be doing to prevent the infestation again.
    I also did the same washing procedure with a healthy croton. Both plants are indoors now, having spent the entire summer on my balcony. Would appreciate your comments/ advice on how to continue taking care of these plants, as I am a little concerned having never faced this problem before. I will be keeping both plants separated from the rest to further control the spread.
    Thanks again for your advice.

    Hi Ray
    It sounds like you have it under control. Check once a week to see if there is any evidence of the insect, if so give it another treatment. Your diligence will pay off.

    how long ( in years ) do basil plants live?
    or how often should they be dug up and replaced ? Mine look great, but are approaching 15 yrs. of age

    HI Dennis
    Wow 15 years, that’s great! Here in the Midwest we can only grow it as an annual. Under best growing conditions, in frost free area, basil plants can live for years. If its healthy and growing well, then there is no reason to replace it.

    Winterover basil indoors
    I am attempting to over winter Sweet Basil in cold Scotland. Two plants are left one a fast growing young plant which 10 growing stems the other and older Spring plant with much less leafage, but still growing. Maximum heat is provided by a warm drying press overnight and sunny window during the daytime.

    Is it better to conserve the plants by reducing the stem cuts, or should normal practice continue?

    Hi John
    It is difficult to over winter basil indoors as they do require warm temperatures, humidity and lots of sun. The amound of indoor light cannot compare to outdoor sun. With low light winter conditions, the plants will grow tall and leggy and produce less leaves. It will not grow as quickly and will not require as much trimming as the normal practice. Cut only what you need. By cutting the stems (pruning) you will help produce a bushier plants but without sufficient light growth will be sparse.

    Thanks for that. I aim to use frozen leaf and oven-dried leaf grounds already set aside. The plants will be left to grow, with warm water every 2-3 days, by syringe, and Miracle-Gro feed every 10 days.

    Next year cuttings will be used, using a propagator, to give more copies of the younger plant to try and maximise leaf output. Can cuttings be made at any time in Spring/Summer, or are hot conditions essential?

    Hi John
    Yes, cuttings can be made in spring/summer, if you have healthy, vigorous stock to work from. They will root quickly in warm temperatures. The other option is to start the plants from seeds in the Spring.

    I was growing a basil plant indoors for a few months when I noticed tiny black dots under the leaves of the plant. Over a period of just a few days, these dots grew larger and my plant started to turn yellow. What could this be, and how do I solve this problem?

    Hi Joni
    There are several bacterial and fungal diseases that attack basil especially when it is in a weakened state. Not much you can do but cut off the infected leaves and hope the new growth will be disease free. Another option is to take a cutting from a healthy portion of the plant and root it. The third option is to start a new plant from seed.

    Hello,
    I have a new basil plant. Im growing it in the window of my apartment. It was given to me by a friend. The plant is about 6 or 7 inches tall but all of the leaves are wilted and the top part of the stems are wilted as well (they all looked that way when I got the plant). The leaves look black but the stems are a very healthy green so I know the plant isnt dead. The leaves, however, smell wonderful I just wished the plant looked healthy. What shoud I do? Can I save this plant? Please help me! Thanks!

    Hi Brittany
    It’s possible that your basil was exposed to cold temperatures or the soil has been kept too wet. Cut off the blackened leaves, if the plant is healthy it will send out new growth between the leaf axils.

    Hello,
    I planted basil trees in pots at my balcony in summer. Everything went fine until autumn, when it’s too cold to leave them outdoor. So I placed them inside my room beside the heater, the warmest spot in the room with the most sunlight. I watered the basil until the soil was very soak whenever the top of the soil dried off, which was about once every two days. Until one point, I noticed tiny (needle point size) black spots under the leaves. The bottom of the leaves also look sponge-like. The leaves turned light brown only on the underside and dropped with slihtest touch. What could be the cause of these spots? How can I prevent or control them? There were also small flies crawling in and out of the soil. Those flies did not seem to eat the basil, but were more interested in kitchen garbage. So I was forced to take the pots outside and leave the basil trees die. I bought a new potted basil from a supermarket later and the same thing happened again within a month. What could be wrong? What should I do to prevent this from happening again next autumn?

    Hi
    A number of things can happen. Keeping the basil plant by the heater is not a good idea. It needs sun,humid, warm air and less water in the winter. It sounds as if the soil was kept too wet allowing fungus gnats to thrive in the soil. Wet soil also leads to root rot and leaf spot disease. Keep in mind that basil is a difficult plant to keep indoors during the winter and usually succumbs to some kind of problem. Let your new plant dry out more before you water again and as soon as the weather is frost free place it outdoors.

    Soil vs hydroponics
    I just bought a “hydroponically grown” basil plant and have put it into a pot with soil mix. I have no idea what variety the plant is. Will the hydroponic version have as much flavor as “typical” basil? Will it survive on a brightly lit Florida balcony that does not get direct sun?

    Hi Donnie
    According to a hydroponic site http://www.hydroponics.net, plants grown hydroponically taste better because nutrients are readily available than when grown in soil. Some essential micronutrients that the plant needs can be tied up in the soil. Your basil should grow well on the balcony.

    What kind of insects is eating your basil? If you have aphids-a strong spray of water will remove most of them. Wipe off the rest with your finger. It’s better than using any chemicals on something you are planning to eat. Slugs, snails and earwigs also feed on basil leaves.

    Yesterday was really windy (gusts around 20 mph all day). I left my potted herbs outside, not thinking anything of it. Today alot of the basil leaves have brown areas on them (not really spots). Is that just bruising from the wind, and if so, is it safe to eat, or should I try to trim it off over the next few weeks? It’s on most of the leaves.

    Hi Stephanie
    Your basil should be safe to eat. You can alway cut off the brown parts. Trim your basil throughout the season to keep the plant compact and continue to produce more leaves.

    Hi! I have basil in a pot indoors under my skylight also near a south facing window. I live in southern california so i’m pretty sure it gets enough sun. However, it hasn’t grown any since I first bought the plant. I’m thinking of pinching it back some, we were not using any because we didn’t want to use it all. but I’ve read pinching actually encourages growth? I was also watering almost every day because the soil gets dry, is this too often? Also I thought maybe it would do better outside. so i moved it. and my boyfriend moved it back in saying it was getting wilty from the sun. I’m not sure what to try next and don’t want to try too many things at once! THANKS!

    Hi Jen
    Your basil plant will grow better if it is outside. Place the plant in a shaded area for a few days and then slowly move it to a sunnier spot. Once outdoors it will require more water. Water thoroughly so that it runs out of the bottom of the pot and then let the soil dry sllightly before you water again. You can tell if the soil is dry by lifing the pot-if its light water.

    The black spots can be insect poop from a caterpillar that is feeding on your basil. Check the plant closely and in the evenings.

    Each year, we plant sweet Italian basil in various containers. For a while, they develop normally, but in just a few weeks the leaves start to develop differently: they are smaller, narrower, more bitter, and a bit concave (v-shaped). They are still nicely green, but the taste is bitter and the yield is less due to the smaller leaves. It almost seems like they “morph” into some different type of basil! Any thoughts or suggestions?
    Thanks.

    Hi Rick
    Basil is best when it grows fast, the leaves are sweet and tender. When it grows slowly, the leaves tend to get bitter and tough. It may be that there is a lack of nutrients esp. in container grown basil. Cut it back and give it a dose of a balanced fertilizer w/ micronutrients. Another possibility is that there is a problem with the roots from overwatering. Make sure the container drains well.

    Its a type of leaf spot disease, that basil is prone to get caused by wet,humid conditions. It can be seed borne. Cut off the diseased leaves, give the plant more air circulation to keep it from spreading.

    Hi!

    I purchased 2 basil plants at an environmental club fund-raiser. (One was labeled butterfly weed, but turned out to be another basil plant!) I planted them outside my kitchen door in one of those rounded grassy hanging pots. There is also a chive plant in with them.

    I’ve been cutting them back as soon as I see the start of flowers or before. The problem is that the leaves are tiny and stiffer than what I’ve seen on basil plants. None of my leaves are those gorgeous, soft big leaves.

    I’ve used this basil in recipes and it’s delicious, but very hard to use with it’s tiny leaves. Should I replant them right into the ground? Use a bigger pot? The one that they’re in is very wide, but not all that deep. Or is it possible I have a different variety of basil? I’ve researched and thought maybe lemon basil, but the flavor isn’t all that citrousy.
    Any ideas?
    Thanks so much!!

    Hi Karen
    There are many different kinds of basil, including a spicy globe or little-leaf bush that produce small leaves. If you want larger leaves get sweet Italian large leaved basil. The plant may be pot bound and could benefit from transplanting into a deeper pot.

Thank you!! 🙂

    Hi Samatha
    I don’t know where the plant was before you bought it. The basil may have wilted from too much sun exposure and or heat. Eventhough, they like full sun and heat if they were growing in a shaded environment and then placed in full sun, they will wilt. Slowly expose it to full sun and make sure the soil is moist but not soggy. If the leaves did not perk up, trim the plant. It will send out new growth, lower down on the stem.

    Hi! First of all, great site. 😀

    I’m VERY new to growing plants, my first attempt: growing sweet basil from seed indoors. On warmer days I try to set the pot out on my porch to get some direct sun. Not in the last month or so because of the cold, windy conditions. It sits in a southern facing window most of the time though.

    Sewed the seeds in May, have three fairly healthy looking three-inch tall plants which are very aromatic. While the leaves look and smell great, the stem is looking dark and/or brown and “woody” I suppose. Could this be over watering? (I try to water once a week.) I live in Michigan, temps are dropping as winter quickly approaches, could that also be the issue? There has been no evidence of fungus, mildew, or insect infestation. Hasn’t attempted flowering yet.
    Some of the lower leaves get light brown spots (look and texture of dead leaves) then drop off completely. Yet the upper leaves look a healthy green, even some tiny new leaves just starting to show. Any suggestions? Or am I just worrying myself over nothing?
    Thanks in advance!

    Hi Sean
    Your plants may have succumbed to some kind of root problem or may be lacking fertilizer. My suggestion for this time of year is to take a cutting of the healthy upper portion of the plant and root it to make a new plant. ou can place the cutting in water and it should root in about 2 weeks.

    In the beginning of summer, I bought a small sweet basil plant at my local health food store and after setting up a 6X6 raised planter, I transplanted it with great success. I tried pinching it back as much as I could, and was even able to propagate two new plants from cuttings (discovered how well they root in water by accident).

    The basil still shares space with a zucchini plant which was plagued by blossom end rot, so in an effort to attract bees to that area to help pollinate the zucchini, I let the plants go to bloom (should have only let one go, but…). Now all three have flowers, a central woody stem, and brown spots on the leaves, but still appear to be growing well (and I have now have zucchini!). I know the leaves would be bitter, but is there anything I can do with them (the brown spots are not powdery, just flat brown and similar to what I have seen on fresh basil packaged at the store)?

    You said in another response that any new plants from a blooming plant will not be as sweet, so would you suggest that I just start over with a new plant? Duh!, I know, but I trouble letting go. Also, since winter is finally here in So Cal (we had some Nov. days that were over 90 deg.!), should I just keep a small plant in a pot, or plant it after removing one of the older plants (we do get below 50 deg. and frost on occasion)? Or, could I keep it in a pot, and bring it inside at night? I’ve never had much success with indoor potted basil.

    Finally, can I just keep letting the original plant bloom to attract the bees, and trim it back every so often, or will it need to be removed? Thanks so much, your site has given me some great ideas. I especially love the suggestion of freezing the basil in oil! Who knew?!?

    Hi Rebecca
    You can leave the original basil in bloom to attract bees but it will eventually die faster or keep trimming it back. As for the new basil, don’t be afraid to cut it back . Pruning will produce a bushier plant with more leaves to harvest. Keep your small plant in a pot so when temperatures drop below 50F you can bring it indoors. Basil are sensitive to cold temperatures. The brown spots can be an indicator of leaf spot disease. Avoid splashing water on the leaves.Also, if your plant is producing healthy new growth don’t hesitate to continue to root cuttings to make new plants.

    Grow basil in water
    I recently bought a live basil plant from a local health food store. The instructions on the plant said that all I had to do was to put the plant in a container with about a 1/2 inch water to keep my plant alive. Is this true? Can my plant survive without having to plant it in soil?

    I’ve been watering it every other day as I noticed all the water has disappeared. I Live in the pacific northwest and we’re still experiencing a mild winter (40-50 degree weather.
    Thank you!

    Hi Carol
    I’m assuming that you bought a rooted basil plant. It is like growing basil hydroponically except for a few missing steps such as fertilizer and sufficient light. Shorterm, your basil will grow and stay alive in water for maybe a few months but it will grow much longer in soil.

    Dried Basil

    I’ve been growing Basil (Tulsi) for the last 2 years and it has grown extremely beautifully. However we have had a very cold and breezy winter last year and the plant got very little sun. It has lost all its leaves and now only the stem remains (which is woody in nature). I water the plant… stem just enough to keep the soil moist and have put it in a sunny spot outdoors. Do you suggest re-potting the plant? Or any other suggestion is welcome.
    Thanks.

    Hi Liz
    Yes, if there is any chance of survival, I would repot the basil plant in early spring. Wait until you see some new growth. If there is no growth, then there’s a chance that the basil is dead and you will need to start over. Basil can succumb to root rot and other diseases after a few years. It might be prudent just to start over with a healthy plant.

    Basil is a warm weather herb, but if it is an established healthy plant that has been growing outdoors for a while, then it should tolerate an occasional below 50F. New tender plants will be more susceptible to cold damage.

First off, they are not big and bushy like all the basil pics you see. They are one stem with about five sets of leaves each. The leaves are turning brown and wilting but the stems still look green and great. I’m thinking I should replant them each in their own pot? Should I? and what kind of fertilizer and soil should i use? This is the first plant I’ve ever grown and spring is right around the corner and I don’t want my basil to die after coming this far! Please help me!

    Hi Amy
    Congrats! It’s not easy to keep a basil plant through the winter. They do look pretty sad this time of year. I usually start new plants from seed. If you want to repot your basil, separate them and plant them in fresh potting soil mix. Also trim back the plant by 1/2 making sure you have the green part of the stem. This will produce a bushier plant. Another option is to plant it outdoors when night temperatures are above 50F. Until it starts to grow new leaves, there’s no need to fertilize when transplanting into fresh soil .

    Hi Betty
    Your basil needs to go outside. Eventhough it get lots of sun indoors, it doesn’t compare to the sun outdoors. Wind is also a factor in producing a sturdy stem on the plant. Pinch the plant to a node so that it will get bushier and produce a stronger stem. Let the plant dry out a bit before watering.

      thanks but cant go outside yet, on the west coast midapril so its still a bit chilly, we havent seen those 10+ days yet. when u say pinch to a node…explain… u mean pinch off the new leaves, i only have one full set (2) and then another set just coming thru or fairly small that would leave some plants with none…. 🙁

      Hi Betty
      A node is enlarged section on the stem from where new leaves or roots will grow. You will have to wait until you have another set of leaves before you can pinch it back. There really isn’t anything else you can do but start new seeds. But here’s a better idea, when you get a second set of leaves take a 3″ cutting (have to have set of leaves and a stem -node is optional ) and root in water. At this time of year, basil will root quickly and you will have a new stocky plant in no time.

    Water-soaked spots on basil
    hi,
    i’m trying to find out what’s ‘eating?’ the basil leaves……if it was mentioned earlier, i must have missed it and i’m still looking, but if someone has input, thanks

    it’s potted in the kitchen with parsley (which is not affected) and the leaves are losing green…..
    there is ‘leaf’ left but the spots are just see-through and very thin….
    i can harvest most of the leaves but is there something to look or to do for the new growth?

    It doesn’t sound like an insect is eating your basil but more like a bacterial/fungal infection. There are several bacterial diseases that will affect basil causing gray-black water soaked spots on the leaf. If so, remove the spotted leaves. Make sure you don’t keep the soil too wet. If it gets worse, take a cutting from the healthy growth and root it to make a new plant. Another simple possibility is cold water injury. This happens when cold water is splashed on a warm leaf surface. It usually happens when the plant is growing outdoors. Avoid splashing water on the plant.

    My container basil plant does not look lush at all. It has grown tall and thin. The leaves are very small and the stalk is getting hard. I want it to look green, lush, and full. What do I do?

    Hi Lindsay
    I would cut it down by 1/3-1/2 to allow new side growth and put it outside in the sun for the summer. I don’t know how long its been in the container. It may benefit from repotting in fresh soil. If the cuttings are healthy, root them to make new plants. Sometimes its better just to start with a new plant.

    Freezing basil tip
    Secret to freezing basil – rinse gently each leaf – dry thoroughly on paper towels with paper towels over the top to keep changing paper towels until totally dry – then wrap two leaves in a small piece of paper towel do with every two and place in plastice freezer bag put in freezer – your leaves will come out looking fresh

    Hi there, each year I buy 3 basil plants and pot. I keep them indoors and they do wonderfully. Once the weather gets warm enough, I move them out to my deck. Within hours they turn almost transculent and crumble at the touch. My back deck is definitely full sun. I am not sure what is happening. When the plant is indoors, it is in front of double doors with windows flanking both sides of it, sort of a sunroom with a skylight above it. Could I be shocking it with too much sun and heat? is it a bad root system b/c I water from the top of the plant and it doesn’t show it until it gets out in the deck?

    Hi Stacie
    Yes, you are shocking the plant with too much sun and heat. Indoor light is much lower than any outdoor light. You need to slowly acclimate the plant to higher llight conditions by exposing it to sun for a few hours a day increasing time exposure with each subsequent day.

    Hi -a few weeks ago I bought a basil bush (20 -30 stalks, of varying heights) at the supermarket and planted it in a trough on my balcony – it has grown remarkably well and tall. I noticed it would wilt if in direct sunlight for too long, so have been gradually exposing it (it must’ve been grown in the shade).
    I have 2 questions:
    1) I woke up this morning to find the 5 tallest stalks (now almost a foot) bent over in the same direction. It may have been the sudden drop in night temperatures. Do I just start bringing them inside at night and wait for them to reassert themselves?
    2) 2 or 3 of the tall stalks have begun sending up little rows -will these become the dreaded flowers? and is it too late to pinch them off? I read that you said we should pinch them a few nodes down –when pinching, should I pinch below a node, or leave the node?
    Thanks so much!!

    Hi Naftali
    If night temperatures are below 50F then bring them indoors, otherwise leave it outdoors. The “little rows” are the start of flowers.
    Best thing to do is cut the plant back by half or several nodes down. Cut it above a node (leave the node)-that’s where new growth will come from.

    oh and what does it mean if the very base (maybe a centimeter out of the soil) of some of the taller stalks looks a bit woody? is this normal? thanks so much!

    As long as its not black or soft then, its normal. As they mature basil will produce a woody stem.

    Pale green basil
    I’m so glad I found your site. I am not much of a green thumb, but I bought a basil plant and for the past couple of months have watched it go from a bright, beautiful green, to a pale and sad light green. I have it on my deck which gets full sun and I live in Tennessee so it’s HOT. After reading these, I think my problem is over-watering because I had it sitting in container that kept the drained water. I hope it can be saved! Also, can you recommend a type of fertilizer that could help?
    Signed,
    Clueless 🙂

    HI Paula
    If your basil is wilting when the soil is moist, then it may have some root rot issues. Make sure that it doesn’t stand in water. It may also need a balanced fertilizer(10-10-10) to help replenish the nutrients that washed out of the soil. Follow label directions for use. Move it to a shadier spot until it looks like its recovering.

    I’ve been growning basil inside with a grow lamp. They have been doing well, but now have tiny bugs on them and everywhere around them. How does this happen? Where do these little obnoxious bugs come from? More important, how can I get rid of them?

    Thank you.

    Hi Pam
    Not sure what kind of bugs you have. If they are fllying around the base of the soil, they may be fungus gnats which occur when the soil is too wet. If so, let the soil dry out between watering.If you can put the plant outside in warm weather.

    What’s eating the basil
    I have 3 healthy basil plants in my garden. Only problem is, something is eating it up, and I mean eaten. What can I do? Put Sevin around plant on ground and slug pellets, too, around plants and the basil is still getting eaten up. Please help! Thanks!

    Hi Barb-Norm
    It difficult to say what you can do for basil esp. if you don’t know what is eating the plants. In addition, you don’t want to spray with some random chemical because this is something you will be eating. Slugs is a good posibility as well as earwigs. Japanese beetle will also do a number on the leaves. They chew holes in the leaves until they turn into lace. If you have Japanese beetles try to protect the plants with a floating cloth during the sunniest part of the day.(that’s when they like to feed) until they are done with their mating/feeding frenzy. If you use a chemical make sure it is listed for basil.

    I have been growing a sweet basil plant. I live in South Florida and keep it inside some days because it seems to wilt in the summer humidity but also try to let it sit outdoors some days. Recently I brought home a mint and cilantro plant. Today I noticed there were spots on the leaves of both the basil and mint plants. The basil leaves have some white-brown spots that look dried out on the top and underneath there are more white spots with tiny black dots. The Mint has the same condition. I noticed a small winged bug in the soil today. I’m not sure what this is or how to treat it, especially if I want to use the plants for cooking. Should I toss them altogether and try again? If so, should I not buy them from supermarkets? Is there something I should be doing differently? Please let me know, I find your information quite helpful.

    Hi Michelle
    I’m not sure what kind of insect is bothering your plants. Try spraying the plants with water to see if you can knock off the insect and possible eggs. As a last resort, try insecticidal soap or soapy water. Spray the leaves and soil surface.
    When watering, avoid getting the leaves wet as that can cause a leaf spot disease, which may also be a possibility. see http://hortchat.com/info/growing-basil/comment-page-1#comment-102681

    Wilting basil
    I have basil plants I started in my window sill from seeds. It has been doing great and thriving. I recently replanted my plants (8 of them) since they were growing so closely together and some were not thriving as well due to taller plants taking up space. I replanted them apart, watered and fertilized them. They were fine except now, whenever they are in the sunlight all of the leaves wilt. After the sun goes down they seem to “un-wilt.” What gives?

    Hi Yolanda
    Your basil plants are not acclimated to the additional sunlight. My guess is that the basil root system is too weak and is not able to supply the leaves with enough moisture when needed, thereby causing them to wilt. Give it some time to establish itself and then slowly move it to brighter light.

    Spiders on basil plant
    Hello,
    I bought a Genovese basil plant about 3 weeks ago, and it looked like it was doing fine. However, there is now a network of webs and a population of tiny little white white spiders using these webs as highways. I’m afraid of spiders, and have no idea what to do. Is there a safe method of getting rid of them? (i.e. one that won’t harm the plant or us since we like to use it in our cooking)
    Much Thanks!

    HI Wessy
    Spray the basil plant with water to knock off the spiders. Repeat after a few days. see if that helps.

    Bitter basil leaves
    I have had my basil plant for over a year now. It has been outside in my garden and since I live outside of Phoenix, AZ the winter did not kill it last year. I was not sure if this was an herb you regrow every year or can maintain for as long as it lives (for consumption not just a pretty plant). The bottom stems are very woody and I did not know until 6 months ago to pinch off the flowers. Since then there are many more leaves. I haven’t used it much except for dry herb. At this point I am wondering if I need to just pull it and start fresh every year so I don’t get bitter leaves? Actually, since I haven’t had much time to cook I am not sure if it is any good. It is super fragrant when I pinch off the tops. We can smell it from 10-15 feet away.
    I have been looking for information and so far the comments I read here have been helpful.

    HI Alison
    Basil can be grown as a perennial in warmer climates. As the plant gets older if you don’t cut it back regularily, the flavor becomes bitter and stronger. Once it is allowed to flower, basil will develop bitter leaves. Give the plant a major pruning. Cut it down 6 nodes or leave 2 sets of healthy green leaves from the bottom of the plant. It should send out new sweeter leaves. Also, take some clippings and also root them in water for new plants. They root in water very quickly this time of year.

    Puckered leaves
    Hi.. I’m growing basil indoor under a florescent plant light. I’m running into a slight problem I think. some of the leaves are growing really funky. Generally some of the new leaves are growing funky. They are bubbly and wrinkly but still green. Something about it doesn’t seem right to me because the other leaves a very broad and open. Is this normal? One thing about the super wrinkled leaves is they smell very potent and a really green so I dunno what is really happening. Please if anyone has any ideas, suggestions or comments ect … please go let me know. Thanks.

    Hi Rabbit
    When basil grows in its juvenile stage, it will grow smooth leaves, as it matures the leaves become puckered or wrinkled which is one of its characteristics.

    Hi,
    I’ve been growing sweet basil from seeds on my sunny windowsill (I know it’s late in the year!) Around the stem of some of the seedlings, there is a layer of white fuzz. I’ve looked closely and haven’t been able to find any bugs. The white fuzz is not on all of the growth. Is this something I need to be concerned about? Thanks for your help!

    Hi Vanessa
    It sounds like there is some mold growing on the soil surface. You may be keeping the soil too wet and not enough air circulation. Scrape it off the soil.

    My basil plant started off great and thrived. Then I changed pots when it got to be time to give the roots more room and the new dirt I added was some recycled soil from an old plant that died of too little water. quickly after the change a strange white film began growing on the outside of the brand new pot… and now there is mold on the dead leaves and soil. There is no mold on the actual plant. There are several brown spots but I’m pretty sure they are just from a little lack of water… what do I do! New pot and soil?

    Hi Abigail
    The white film on the outside of the pot could be excess soluble salts either from fertilizer or using softened water, perhaps even the old soil. Remove the moldy leaves and scrape off any mold on the soil. Basil can develop a leaf spot disease. Instead of repotting, take a cutting from the healthy part of the plant and root it for a new plant. They root quickly this time of year.

    Hello. I bought this plant at a young stage from home depot.I live in Florida. My basil plant is about 3 months old. It has now lost its bottom leaves & only has green on the top. One looked like it has a white pod inside so I quickly clipped the top off. The stems are woody & I guess my question is this… How long do these plants live? Should it last me a longer time than 3 months? I have 4 plants in a 8″ ceramic pot. If I cut down the wooden stems, would they grow back? Or should I try & seperate them or would it maybe kill these plants? It’s probably about 5-6″ tall. Now it’s just has a few leaves on top. What should I do? Thank you for your expert advise! This plant means a lot to me because it’s the first plant I have ever grown in a pot!!!
    I am a new green thumb trying to succeed. 🙂 Thank you.

    Hi Rhonda
    It sounds like your basil plant has some growing issues. Why not take 3″ cuttings from the top of the plant and root it in water to make a new plant. This way you’re trimming the plant and if it doesn’t regrow, then you will still have a new plant to grow. Careful not to overwater the plant.

What do i do ? i really dont want to loose my plant !

    Hi Ash
    Have you fertilized your basil plant? If its in a container it may need more nutrients to keep it going. It may also be getting a leaf spot disease. Avoid splashing the foliage with water and remove and fallen leaves. Make sure you let the plant dry between watering.

    Powdery mildew on basil
    basil leave has white spots how it can be avoided and is it safe to eat such leave.Please advise which type of fertiliser to use.

    Hi
    The white fuzzy spots on basil leaves is powdery mildew. To avoid powdery mildew, grow your basil in a well ventilated area in full sun. Also, avoid water on the foliage. I wouldn’t eat the infected foliage. In fact, remove the infected leaves to control the disease from spreading.
    Feed your basil with a balanced 10-10-10 fertilizer that includes micronutrients.

    Hello,

    I bought a lettuce leaf basil plant in a small pot a week ago from Walmart. I’ve been watering it moderately (when the soil is dry). It is placed indoors beside my balcony for sunlight. I woke up today and saw the that the bottom side leafs have suddenly dropped/wilted. I felt the soil, it was completely dry even though I had just watered it the night before. There is also a small black spot on one stem, Here are my questions:

    Has it been infected with a fungus? Fusarium wilt?
    Is it safe to eat if it has been infected with Fursarium wilt?
    Here’s a link to a photo of my plant for reference. You can see the wilt and small black spot on the middle stem.

    Thanks for your time,

    Hey Dina
    Your basil plant looks fine. The brown spot may be a bruise or the start of something. If you’re concerned, pinch the stem below the spot. It will send out more growth from the node and make the plant bushier. Remember the more you pinch basil, the more leaves you will have to eat. The plant is actively growing and is using up more moisture, so keep a close eye on how much water it gets. Be careful not to overwater.
    Your basil plant would look a lot worse if it has a fungal infection. By the way, I would eat the leaves if it was infected.

    Fungus gnats on basil plant
    Hi,
    I seem to be having an issue with tiny little basil flies. I believe my problem is too much water and I will be letting my plants dry a bit more between feedings from now on. However, I would like to know if I can eat the Basil I currently have as well as keep growing it. I did see one or two leaves that had turned brown but nothing other than that, everything else seemed healthy despite the little gnats. I read another post that you responded to and I was wondering if I could continue to use the basil I had by changing or drying out the soil or if I should just toss the basil plants all together. Please help!! Thanks.

    Hi Renee
    You can eat the basil dispite the gnats, just wash the leaves before eating them. If you can, put your basil outdoors and let the soil dry slightly between watering-that should take care of the gnats. They are more prevalent indoors and harder to get rid of.

    Hi, I am impressed with your diligent replies to growers’ questions. I have three basil plants. One is doing fabulously, the other two are in smaller containers with geraniums and purple basil and want to bloom (now I know I need to cut them back- thanks). The problem is they have an odd smell that others on the internet have described as cat urine. I don’t notice this on my other basil plant. Do you know the cause?

    Hi Cheryl
    The black powdery substance is sooty mold-a sign that the basil was infected with a honeydew secreting insect like aphids. If you ask 10 people 5 out of 10 will say yes its ok to eat it. I’m part of the other 5 that would rather not. It’s up to you.

    Hello,

    I live in arizona and have a basil plant growing in a large pot. It did wonderful on my apartment patio. I recently bought a house with a small back yard and brought my basil plant with me. After a couple weeks I noticed entire leaves missing. Whatever is eating it ate ALL the leaves off in a four day period. I didn’t see any chewed leaves, they just totally disappeared. Now all I have left are stems. The stems are starting to produce new leaves but I’m afraid they will soon get eaten. I’m not sure what’s eating the leaves or how to protect it. I’d love some suggestions!

    Hi,
    I have a small sweet basil that I bought at the grocery store a few months ago, and I seem to be having some problems with it. I keep it inside in my kitchen. At first, it had lots of big green leaves and was nice and full. Now it seems to be getting taller and spindly, with a lot fewer leaves, and some of the leaves have started dropping off. I thought it might not be getting enough sun as the days started getting shorter in winter, so I bought it a grow light and leave it on for most of the day. I water it fairly regularly, maybe 1-3 cups of water every week on average (for a 12 inch diameter pot) I think the drainage is good; the water seems to run down the inside of the pot quickly and collects in the little trough underneath it. I try to rewater when I notice that the little trough is dry.
    Recently, I noticed that there seemed to be something happening to the leaves. They were turning brownish and wilty (crispy and dry, like dead leaves) from the tips down the outside edges, and some of them had holes in them or ragged edges. I noticed it most on the little tiny leaves at the very top of the stems’ they were almost entirely brown and crispy. I thought it might be insect-related, though I didn’t see any definitive evidence of insects on my plant. I started spraying the leaves every night with a mix of garlic oil, chili pepper and dish soap in water, but I can’t speak to the results of that, as it has only been happening for a few days. I notice that the leaves are still getting browned and crispy overnight, though. I check in the morning and there are browned tips and edges on some leaves. I’ve been taking those leaves off and throwing them away, but I am afraid of removing too many leaves and harming my plant.

    So, to sum up: A new basil plant, maybe 3-4 months old, started out with good growth but is now losing leaves and getting spindly, well-lit and watered, but getting browned and crispy leaf tips and edges. what can I do about this?
    Thanks for your help!

    Hi Kelsey
    Basil needs warm temperatures, lots of light and humidity to grow well. It’s very difficult to maintain such an environment indoors during the winter. Several factors can affect the browning tips- over and under watering, low humidity and insects. The grow light can help, I would try trimming the stems to stimulate new growth to make a bushier plant. Don’t like to be the bearer of bad news but chances are the plant will barely survive thru the winter. Best of luck.
