Growing Avocado

I have an avocado plant that we started from a seed (pit).  What are its requirements – soil, water, light, etc. for optimal performance??

Avocado makes an attractive houseplant and a great project to try with the kids. Plant in well drained potting soil. When watering, soak the plant so that all the roots get wet and then allow the soil to dry before watering again.   You may have to water more often in warmer weather. It does best in partial shade (bright indirect light)  and will tolerate temps of 55-65F for a few months. Excessive heat, dry indoor air and excess fertilizer can cause leaf drop and marginal browning of leaves.You can increase humidity by placing it in a pebble tray or mist around the plant.   In  Spring start feeding it with 1/2 strength houseplant fertilizer that includes micronutrients(zinc).  If you can, place your avocado plant outside in the shade for the summer. It will enjoy the warm, humid air.  Once the stem reaches 12″ cut it back by half to a node to control the size and shape. It will not flower or bear fruit indoors but makes a great houseplant.  Hardy in zone 9-11

How to grow an Avocado plant from a pit.       start an avocado plant

Choose a nice ripe avocado for guacamole and save the pit.  Insert 3 toothpicks evenly spaced, half way up around the pit. Suspend the pointed end up over a glass of water making sure the bottom touches the water and stays moist all the time.  If the water evaporates, add more and change it every two weeks.  In 2-6 weeks, you should see the pit crack  and a fleshy white root emerging from the bottom. If not, start over.  Once well rooted, carefully plant the pit 1/3 exposed into a 6″ pot in a well-drained soil mix and place in bright indirect light.  Keep the soil moist but not wet.  When the plant is 6 inches tall cut it back by 1/2 and  then again when it is 10-12″.  This will promote  fuller and healthier growth.  

Another way to start from seed. Cut off 1/4″ of the tip and place the rounded bottom into soil- deep enough so that only the flat end is showing. Water and keep the soil moist.

Plant tips
Low light will produce to a tall, lanky plant.
Leaves will yellow and drop in wet soil.
Brown leaf margins and leaf drop indicates that the soil is too dry
Brown leaf margins-fluoride damage
Brown tips- salt accumulation.

    I HAVE AVOCADO TREES PLANTED AND THEY ARE DOING FINE. I HAVE HEARD IT WILL BE ALL MOST IMPOSSIBLE TO GET FRUIT.IS THIS SO? IF SO HOW CAN I GET THEM TO PRODUCE? I LIVE IN LOUISIANA AND THE STONES THAT I USED WERE FROM FL

    The question is are you willing to wait 20-30 years for the seedling to produce fruit and once it does will the quality of the fruit be worth the wait. Grafted trees from local nurseries planted in the spring will take less time to produce fruit. One recommended variety is Mexicola Grande which is hardy in the low 20’s. Enjoy your avocado plant as an attractive houseplant.

    I planted an avocado pit about last summer. It is about three feet high and has a nice round shape. I want to move this tree to a diffrent location, Right now it gets sun most of the day. I need to move it back a little that would put it to have more shade. Can I replant this small tree to its new location now in the middle of summer or should I wait ? Would transplanting this tree cause harm? Would the new location be a good choice. I live in Florida. Thanks for your tip?
    Need advice!

    Best time to plant is in March-June before the heat of summer. Avocado trees will grow in a shaded area but will not produce fruit unless in full sun. Plant where it can get protection from wind and frost. The shallow tree roots will need lots of room to spread(up to 20 ft) and good draining soil with a ph 6-6.5. Plant in an area with no lawn so there is no competition with the shallow roots. For more info go to www. ucavo.ucr.edu

    Transplant shock
    I transplanted a three foot avocado tree about a week ago. Now the leaves are wilted and seems very dry and crisp. Should I cut off these leaves for new growth? There seems to be little spurts that are on the branch. I thought that maybe if I prune off the wilted leaves that this would help the new spurts. What should I do about this, and is there anything I should feed the plant with at this time. Its been very warm I live in Florida.

    HI Denise
    It sounds as if your tree is going through a bit of transplant shock. The roots were disturbed and now need to regrow to support all the leaves on top. Since the leaves are dry and crisp they are mostly dead and can be cut off. The only thing I would suggest to feed it at this time is a root starter solution that will stimulate new root growth. Make sure it gets adequate water especially in hot weather.

  • ROBERT

    I have an Avocado tree with small green, what seem to resemble sm peach’s. I’ve never seen sm Avocado’s before. Could these be the fruit? If so how long before it matures? Thanks

    Sounds like the fruit. The harvest time for avocado depends on the variety.Mexican variety ripen in 6-8 mo. from bloom, others Guatemalan take 12-18 months. Avocado is usually picked unripe and then allowed to ripen. There are subtle signs that let you know when its ready to pick.

    I HAVE 3 AVOCADO TREES RANGING FROM 3 TO 10 YEARS OLD. THIS YEAR THEY BORE NO FRUIT, HAVE NO NEW GROWTH. THE LEAVES ARE SMALL SPARSE BUT GOOD GREEN COLOR.I WATER THEM DEEP WHEN THE WOOD STAKE THAT I HAVE NEAR EACH ONE IS DRY. I HAVE FED THEM WITH AVOCADO FERTILIZER THREE TIMES THIS YEAR.THE SOIL PH SHOWS A 6.5 AVERAGE. THEY ARE IN FULL SUN.IN SANTA BARBARA CA. I WOULD APPRECIATE ANY SUGGESTIONS. THANK YOU.

    I just transplanted a 6 ft avocado young tree. A lot of the root system got damaged. Now all the leaves are wilted, some completely dry, and I’m just scared to death the tree is going to die. I’ve been watering the tree often adding some root starter. The tree is also in direct light and it’s not helping we are having a heat wave this week. Any help on what to do? can the tree survive even if all the leaves are wilted? should I create some sort of shade for it? Please help!!

    Hi Andres
    Create some sort of shade (umbrella) so that the leaves won’t loose so much moisture and pray for cooler weather. The tree can survive as long as the leaves don’t drop.

  • Andy

    I have just moved into a house in Sydney, which has an Avocado tree. It’s pretty big -must be about 20-30 years old – and at this time of year has plenty of avocado on it. However, they look healthy but with a black ‘mould’ at the bottom. When we pick them early, the fruits don’t have the mould, but don’t seem to be ripening after a week or so. Does anyone have any advice for me please?

    Hi Andy

    Maybe you’re picking the avocado either too early and then too late. Check out this site. there is some good info on When to pick avocado http://www.ucavo.ucr.edu./AvocadoWebSite%20folder/AvocadoWebSite/General/Answers.html#anchor728187

  • John Pommerich

    1. how can i tell when the avocado is mature enough to pick and ripen?
    2. I have a decent crop this year. This the first year I have abunch of small ones about the size of my thumb? Can I eat them? I opened one up there is no pit.

    Hi John
    Pick a couple of avocados and try to ripen them. “If the fruit shrivels up and is rubbery instead of soft, then it is not ripe. Keep picking fruit every few weeks. “1
    It may be that the flowers did not pollinate properly and produce small elongated fruit that are called “cukes”. You can pick and eat them when they are ready. These are sold as “cocktail” or finger avocados.

  • Ryan

    Hi – I’ve looked everywhere but can’t find anything about my Avocado tree. I have 4 in my garden, but on only one of them the fruit reaches 3-4 inches and then turns completely black and falls off. It is a very mature tree, but gets no more or less watering than the others.

    Hi Ryan
    It could be an insect problem or poor pollination. See the above link to avocado Q’s. Take a sample to your local extension office and see if they can identify the problem

    I HAVE A SMALL AVOCADO PLANT I AM GROWING INSIDE MY UPSTATE, NY APARTMENT…NOT REALLY AVOCADO TERRITORY, I KNOW. IT HAS BEEN DOING FINE UNTIL RECENTLY WHEN DRY BROWN SPOTS STARTED SHOWING UP ON THE LEAVES. THE BROWN SPOTS STARTED ON THE LEAVES TOWARD THE BASE OF THE TRUNK AND HAVE MOVED UP. NOW THE BOTTOM LEAVES ARE STARTING TO FALL OFF. WHAT AM I DOING WRONG?

    HI Terianne
    Several factors can cause browning of the leaves on your Avocado. If the leaves turn brown at the tips and margins, or show petiole/leaf rot then the problem may be excess soluble salts caused by using softened water, hard water or overfertilization. Plants can only utilize a small amount of salts; any excess becomes toxic to the plant, irritating the roots and causing leaf burn as well as changing the soil ph. To flush out these excess salts, water the plant until it pours out from the bottom of the container. This method will leach out some of the salt build up. Use distilled, spring, rain water or melted snow when watering your plants and repot the plant in fresh soil in the spring. Low humidity, underwatering, disease and insect infestation will also causeleaf spots and leaves to turn brown and drop.

  • Barb Kelley

    My avocado tree produced good fruit last year (fall season of 2007 into 2008). This year I have gotten no fruit. What can I do to get fruit this coming fall/winter. I live in St Petersburg,

    HI Barb
    The tree can bloom as early as Dec.-April, if there is a frost during that time, it can damage the flowers and produce no fruit. Fortunately, the avocado trees bloom over a span of several months and later bloom can still produce fruit. You are at the mercy of the weather.
    U of Ca. has a great site with lots of info on growing avocados outdoors.

  • Natasha

    I am staying in Malaysia, Borneo island. I had an avocado tree which is 4 yr old. She has started to bloom quite often since last year but never bear any fruit. Should I do anything to help her? ?Is it true that I have to wait 10 years?

    Hi Natasha
    Yes, it can take 10 years. It may not be mature enough to produce fruit yet. It takes many flowers to set fruit. The proportion can be 1 fruit to 10.000 flowers.

  • carol free,am

    I planted avocado seeds approsimately 12 years ago. The plants have always been healthy. this year, for the first time I have lots of blooms. I think this means I may have avocados. there are plenty of bees around the blooms. is there anything else I can do to help with polination?

    Hi Carol
    The best you can do for your avocado tree is to keep it stress free. Don’t over or underwater it. Fruit set is best when temperatures are around 65-75F. It is thought that pollination is improved when there are more than one avocado tree present.

  • irene

    i have two avocado trees that i got from my friend she grew them in her backyard when she moved we took them out of the ground and put them in our yard but it has been two days and they look like they are dying what should i do thank you

    Your avocado tree is suffering from transplant shock. Make sure it has adequate moisture, provide some shade (if you can)for the summer months and water it with a root stimulant to get some root action going so that they can feed the rest of the tree. Pruning it by 1/3 could also help-that way the roots will have less to feed.

    Avocado roots
    I just want to help make a note about Avocado trees, if you decide to have them in the ground of your place, careful not to have it way to close to your house for the plant itself will develop a very large and powerful root system that does spread. Here in Hawai’i, Avocado trees are very common and many foundations are cracked cause of the roots.

    Great info. Mahalo

    I recently planted a 3-4 year old avocado tree, it is about 8 ft tall, but lots of the tips of the leaves have gone brown and many feel dry, despite watering it morning and evening… anyone got any suggestions?

  • I have an approx 8mo. old avocado plant that I planted from the seed (its fruit was delicious!). The upper leaves as well as the lower leaves are drooping down. I watered it a lot and the upper leaves started to raise a little. But the lower leaves are still quite droopy. The leaves are a very nice rich green. I live in Sacramento, Ca. The temp is pretty hot but he (Mr. Avo) lives inside and is in temp of around 78. Although when its in the hundreds he is in about 86 degrees. I have never fertilized him.

  • Kathrine

    I have a Lola Acacado tree and I noticed black markings on the stems resembling mold. When I touch the stems the black stuff some of it comes off. Plus the leaves look wilted and looks sick. What should I do and please let me know what it is and what action I should take. I live in Orlando, Florida, where it has been raining so heavily recently. I also have another avacado tree a brogan and I am scared it will also get contaminated too. Please help! Thanks,

    Hi
    I live in northern Alabama. I started from a avocado seed and now it is about 5 months old. Do you think it will live if I bring it inside each night and take it out in the morning.

    HI Neeccee
    It should be fine outside in a warm protected area, provided you bring it in when night temperatures get down to the 40’s. You can also grow your avocado plant inside as a houseplant by keeping it in a bright, sunny window. Although indoors, it won’t get as much light compared to outdoors.

    Fungus gnats
    Hi, i am growing an avocado from seed, it is almost a year old and looks healthy. however, there are many insects, similar to fruit flies, hopping in and out of the soil. How do i get rid of all these quick, winged insects?

    Hi Jessica
    It sound like fungus gnats in the soil. Let the soil dry out between waterings.

  • Winter over
    I have grown several avocado trees from fruit seed. They usually die due to neglect. The latest one is three years or more old. Last year we planted it outside–our apartment is too small for big house plants. It dropped all of its leaves, then in the spring, it put out new leaves and a second “tree”. Now that it is turning cold, we banked the roots with pine needles, and covered it with a trash can. Question? is there a proper way to keep it warm through NC winter?

    Hi Esther
    It sounds like an easy way to protect it. I’m not sure if it will work. It may need some air circulation to release the hot air that can accumulate on a warm sunny winter day. The trick is to keep it at a steady temperature. You can try burying or covering it with soil like they do with fig trees in colder areas.
    Let us know how you tree survived.

  • Evadnee

    I have read that trees grown from a avo pip will never bear fruit. Is that correct? I am growing the pips from 2 old established trees from my garden and not from a grocers. They are growing very well thus far.
    I have also read that you need 2 or more trees next to each other- one male and one female. Is that correct?
    There is so much conficting information on the net.

    Hi Evadnee
    Avocado grown as an indoor plant or in a container have a slight chance of producing a fruit. Grown outdoors in the ground is another story. For best pollination, it is better to have more than one tree but a single tree will produce fruit. The flower starts as a female and then turns into a male flower and other types of trees produce flowers that start as a male and then a female.

    Avocado plant care
    I have two avacado plants that I started from pits – they did pretty well, but now they look like they are dying – there are definitely gnats – so I suspect this is the problem – I have been letting them dry out pretty well and try not to over water – they get morning sun. I have read to use sticky bug traps to try to get rid of the gnats, as for the plants, the leaves appear dry and all droppped from one plant, but the other has kept it’s leaves – the one that dropped it’s leaves is sprouting new ones on top – should I prune these back? I clipped the stems when they got about 6 inches tall and they leafed out – now they are aobut 10 inches tall. I’m kind of excited about actually getting these to go, so would like to learn about the plants care – any suggested reading or sites would be appreciated.

    Hi Becky
    If you cut back the tip to 6 inches, then you should get new growth coming from the stem below. This will promote bushier growth. See the article above for more growing info.

  • Tree suckers
    My daughter has an avocado tree that was there when she purchased the house. The tree has 2 large thick branches growing out on it’s side about 6-8 inches from ground. If I remove a branch close to trunk and transplant it in another area of the yard, would the tree keep growing or just simply die?

    Hi Iliana
    You would have to make sure you have adequate roots for the small tree to survive. The branches close to the tree trunk are probably suckers(water shoots) that grew from the roots or trunk and are usually pruned.

  • Valerie

    Live in So Cal. Planted a young Hass avacado tree about 4 years ago and it has only produced 4 pieces of fruit (which critters stole before ripened :C ). Every year the leaves turn brown and fall off just before summer begins. However, this year I noticed an additional problem, most of the branches are split on top and have a blackened look inside them. The tree is about 20 feet tall now but still no fruit. Should I give up on this tree?

    Hi Valerie
    Before you give up on the tree consult your local extension office or an arborist.They should be able to help you. It sounds like the tree has some issues that need to be dealt with. Sorry I can’t be of more help.

  • Dave Hong

    I have an avocado tree that is about 10 years old and it started bearing fruit 2 years ago. 8 the first year, 10 last year and this year there are dozens of fruit being set but don’t know how many will stay on. Is there anything I can do to help the fruit to stay on?
    Also there is a large branch thet has grown out from below the ground. I hadn’t paid much attention and now the thing is 1″ diameter and 10 feet tall. It looks different from the rest of the tree and has no flowers at all. Can I safely remove it or should I leave it alone? What is the best way to remove it if It needs to be removed?

  • Pat Robair

    My avocado pit finally started growing roots after several weeks. It just grew a stem a few days ago. Now it seems to have white crusty lumps (like sugar) all over the stems!
    It seems to have happened overnight! What could that be? Is it worth keeping?

    Thanks, Pat

  • I’m worried. My avocado plant is one year old, and at least 2.4 ft tall. One week, I noticed that it had several little leaves sprouting at the top, and then, after a week and a half, I noticed that the top of the plant turned brown. It was underwatered. I’ve since cut off the brown part– but without the top of the plant, will it continue to sprout and grow? Does this make sense? Is there any way to fix it?

    Hi Judah
    Are there any leaves left? If the roots are healthy, the stem may send out new growth from the nodes along the stem.

    Transplant shock
    I just planted my Avacodo tree. It was in a 24 inch wood container. The tree is anout 6 feet tall. I loosened the rootball before planting. Within a couple hours all of the leaves are drooping. I thing it has transplant shock. Will it survive? And if so, how long will it take. Thanks Jeff

    Hi Jeff
    It will take a few days or longer for your avacodo tree to recup. Make sure it gets enough moisture and place it in the shade until it perks up, then move it to a sunny spot. You can also feed it with a root starter to stimulate new root growth.

  • Jill

    Something is eating the leaves on my tree in (So. Cal). Even newer baby leaves are eating it. What could this be and what is the best remedy? There are about 10 tiny avocados on the tree that I hope to eat one day.
