Growing Avocado

I have an avocado plant that we started from a seed (pit).  It is now one year old and not doing so well. What are its requirements – soil, water, light, etc. for optimal performance??

Avocado makes a nice houseplant and a great project to try with the kids. Plant in well drained potting soil and water when the top 1 inch feels dry. It does best in partial shade/ low light and will tolerate temps of 55-65F for a few months. Excessive heat, dry air and excess fertilizer can cause leaf drop and marginal browning of leaves. Feed in the spring and place it outside in the shade for the summer, it will stimulate new growth. Once the stem reaches 12″ cut it back by half to control the size and shape. It will not flower or bear fruit indoors as the commercial fruit bearing avocados are vegetatively reproduced. Hardy in zone 9-11

    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

    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.

    I am trying to restore a lemmon tree that encountered a mushroom fungus a few years ago. This last citrus season it looked liked the tree had potential, it actually was very green and became bushy again and produced three lemmons. I cut back all the weeds under the tree added some controlled release fertilizer (14-14-14) and some top soil. the tree truck seems to be a bit flaky and maybe rotten at the very bottom . What should I do further to help estabish this tree?

    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.

    Hi Art

    I have been growing avacodo seeds from Kellogs organic multi purpose soil. they are around 18″ tall, in the same 12″ pot and are doing well on a mist system. black army ants and nats are attacking the new growth and leaves. How do I prevent this? Thanks in advanced.

    The gnats are indicative of moist soil, you may want to let the soil dry out between waterings. Do you have any sticky substance on the leaves?

    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.

    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

    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.

    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.

    I am sprouting several avocado trees from seed (from inside haas avocados purchased at the grocery store). If grown indoors with grow lights, will they ever fruit? Also, I live in zone 8, bordering zone 9 – if I were to have them outside during the year except for the short winter, when I will bring them inside, will they produce fruit?

  • 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.

    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,

  • vince

    Hi,

    I have an avacado pit that I planted indoors about 10 years ago. It is in a 12″ diameter pot for a few years now and is about 6-7 feet tall. The leaves brown around the edges pretty quickly and then fall off. I would think I am not over watering it, as I do have water running out the bottom and the pot takes a lot of water. Coments and suggestions welcome!

    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.
