How to Grow an Avocado Plant from Seed

If you ever wanted to know how to plant an avocado seed and grow your own avocado tree, then you have arrived at the right place.

Your self-grown avocado tree may itself be able to produce fruit one day, but it may take 4 - 6 years. Until then, you'll have a really unusual houseplant to look after.

Avocado trees can grow to almost 70 feet tall, given the right conditions, so if you need to keep it as a houseplant, you will want to pinch out the growing tip to encourage it to bush rather than grow straight upwards.

Growing avocado seeds is fun, and you get to eat a delicious avocado too. Simply buy an avocado, take it home, eat it, release the seed (which is huge) and carefully clean it under cold or tepid running water.

Any flesh left on the seed with inhibit germination, and encourage rot.

Dry your seed completely, and now you are ready to plant.

There are two methods that I know of to get an avocado seed to germinate, and I will tell you both here so that you can take your choice.

How to plant an avocado seed

The common method of growing an avocado seed is to insert two or three cocktail sticks into the fleshy side of the seed, and suspend over a glass of water until it sends a shoot downwards to take a drink.

The bottom (rounded end) should be actually sitting in the water. You may need to top up the water levels to ensure it doesn't dry out.

If nothing happens by the end of six weeks, it probably isn't going to sprout and should be discarded, but give it that length of time, just in case. They are quite slow at germinating.

Once it has sprouted, it can be planted in a compost filled pot, root downward. Leave the tip of the seed above the soil level.

How to plant an avocado seed type 2

The method above never seem to work for me, and generally the seed just rots.

Of course it could be that it just hates thetap waterhere. It's salty and chemical-laden. Avocado trees hate saline water, and no doubt their seeds do too.

The other method I have had some success with, involves taking the seed and planting it directly into a compost filled pot, rounded end downwards.

Water in well, and leave to drain.

Then pop the whole pot inside a plastic bag and seal. Place in a warm cupboard. Light is not required at this point, and wait for signs of a shoot at the top.

Bring out and place on a sunny window-shelf. Leave in the bag for a day or two longer to allow the fledging plant to adjust, then take the bag off and put a saucer underneath the pot to which you can add water for your baby avocado plant to drink.

This method also avoids the shock of moving the seedling from water to compost.

Growing on your avocado seed

Your avocado seedling can be placed in a sunny position and given frequent waterings.

Let the soil dry out between waterings, and always water from below.

Never let it sit in water that its not drinking up, so if after an hour or two there is still water there, throw it away (the water that is, NOT the plant!).

More plants die from over-watering than from under-watering.

Though not in my mum's house - she always forgets to water hers and they usually all die. Her cactii do incredibly well, funnily enough.

Your avocado is a quick growing tree, so be prepared to have to pot on into bigger pots at least once a year or more.

As I said above, pinch out the growing tip to try to make it grow more side shoots. That way it won't grow so tall.

Pollination of Avocado Trees

Avocado trees grow in tropical and sub-tropical parts of the world. They hate frost so if you live in an area prone to frost, you will need to keep the plant indoors, though you may put it outside in the summer if you have a nice sheltered spot available.

Your avocado tree may produce fruit after 4 - 6 years, but the tree itself is only partial self-fertile.

This is because its flower are male one minute and female the next.

How weird is that?

There are two types of avocado cultivars, type A and type B.

In type A, the flowers open in the morning as female and close at the end of the day. The next day, the same flowers open in the afternoon as males.

In type B, it's the opposite.

They open as female on the first afternoon, and the next morning open as male.

As we need both male and female to be open at the same time in order to pollinate, this is quite difficult.

What we can do, is wait until a male flower opens and collect some pollen on the tip of a small paintbrush or similar. Put the brush into a plastic bag.

When we next see a female flower we can carefully dab some pollen onto the stigma and then let nature take its course.

The fruit of an avocado tree is unlikely to be like the fruit you bought the seed in.

This is because avocados are commercially grafted by growers to ensure continuation of the exact trees and cultivars they have grown to produce the fruit.

If you live in a tropical or subtropical area, you can plant your avocado tree out in the garden. They like well-drained soil but hate alkaline soils with high salinity. If you have the latter two, keep your avocado trees in pots.

Grow in a sheltered part of the garden as they dislike high winds, and indeed high winds can ruin any potentialcrop.

In view of its potential maximum height of 70' (20m), it is advisable to plant away from the house, to prevent future problems with roots working their way into the foundations of your house. Normally, trees roots will spread 1 1/2 times their height.

If you really want to try growing your own avocados, why not buy a ready made avocado tree from Amazon that will possibly fruit as early as next year?

Where you can grow avocado trees out-doors

Avocado trees grow well in:

Mexico, California, Arizona, New Mexico, Texas, Florida, Ecuador, central America, Malaysia, the Philippines, New Zealand, Australia, Sri Lanka, India, Vietnam, Indonesia, Spain, Crete, Peru, South Africa, Chile.

Thank you so much for this hub. I've always wanted to know how to do this. I love avocados!

You're welcome. It's great fun, but if you want to pick your own you are probably better off buying a tree grown by a specialist. I'm surprised at Amazon's prices. I can buy them in the local market - 5' tall or thereabouts - for about €15 ($25) each.

Hi IzzyM,

I tried the water method many years ago. I didn't have any luck with it. My mom, however, did.

I would love to try this again, however, I only have one tiny window with no sill that gets full sun. So basically, the only light I get in my home is from all exposures, but only the small window with an eastern exposure.

Should I bother to try again?

IzzyM profile image

IzzyM 5 years ago from UK Author

I would anyway. The last one I grew lives at an east facing window. It doesn't grow an awful lot but it looks healthy enough.

Would love to grow one to maturity, at least to the fruiting stage. Unfortunately the climate here may not support the fruiting. However I have tried the first method wothout much success. I shall try the second way to see what happens. It's a shame to throw the seeds away without trying. Thanks.

I grew my avocado trees in Scotland so it can be done. They are just houseplants of course. I started to grow some here but they didn't survive their first summer - its just too hot and dry here and the tap water is awful!

Great Hub. I love avocados and have tried the water method so many times with no luck at all. I did not realize that there was another way to grow them. I was just signing out of hubpages and saw your hubpage on the sign out page. So glad to have found it. Thanks so much. Now I will be off to the store to buy some avocados.

IzzyM profile image

IzzyM 5 years ago from UK Author

This hub is on the sign out page? LOL Thanks Hubpages! (not sure if that's good or bad)!

Susan, the second method is a bit hit or miss too, and I think that's because it depends on the seed. Worth a try :) It works for me :)

If we're all growing our own (and saving a fortune) it is worth noting that avocado fruit, like bananas, ripen off the tree. Pick them when they are green and firm, then they will start to ripen.

I'm attempting to get one started by growing it in water. So far no luck, of course I think it has only been about 3 weeks and not 6. Guess I'll give it a few more weeks before tossing it. You are right though that some seem to sprout faster than others. Thanks for sharing all the tips. :)

Thank you, thank you, thank you! I'm so glad I 'ran' into this hub, although I believe, nothing is by accident. Just this afternoon at lunch I made guacamole and removed the pit from both avocados. I placed them inside the water glass thinking this was what I remembered had to happen. And, now-you're hub! So helpful. Glad it made it to the featured hub section.

Yes they need either a tropical or a subtropical climate but you can grow them indoors in other cooler climates :)

My avocado stone is just dangling in a little water ,but still hasn't sprouted any greenery? its been around 10 days I just keep topping up the water ,as I know the air conditioner makes it quite dry inside?

Loved your hub ,thumbs up!

IzzyM profile image

IzzyM 5 years ago from UK Author

Thanks :) Keep topping the water up so that the rounded part of the stone is sitting in the water. It can take up to 6 weeks to germinate so it's early days yet. Good luck!

Great hub! I always watched my parents try to do the water method growing up in California. I was never successful at it. I got tired of it and just threw three seeds in their own dirt and watered. To my surprise, they all sprouted. I have one left (they're tempermental to being moved and I've even changed states with them)that is about two years old. Everyone that comes over to my house comments on it. We love it! Good luck to all. Avocados are great fun.

I have always had good success using the toothpick/glass method, getting my seeds to start. Problem for me is, every time they get going, they die shortly after. I live in a high altitude area, so I am sure the cold and such has some to do with it.

Nice hub tho,

Good job

You need a nice warm conservatory or heated greenhouse so they get plenty of warmth and sunshine :)

Now this is a very unique hub. Great info and thank you for providing some very useful info. If more people would plant seeds instead of just throwing them away, we might actually be able to help restore some of the damage we're doing to our planet.

Absolutely Nate! I seldom throw any seeds away, and so have a mini forest of all sorts growing - apples, lemons, oranges, avocados etc. Reforestation is what we should all be aiming for :)

I started my tree from the water and 2 months now he's a foot. Going great and fast but the sorta new bigger leaves are droopy. Granted the lower ones dry out and are cut off and there are new leaves up top. In a 3 lb. Butter bin. I don't wanna lose him any advice?

IzzyM profile image

IzzyM 3 years ago from UK Author

Over-watering? Try to leave him on the dry side for a few days and see if he improves. Sorry that's the only thing I can think of. You don't want to re-pot him because if he is suffering now, the shock could kill him.

If his compost is already on the dry side, try increasing his watering. If there is a heatwave where you are his watering needs will have increased.

Very Interesting! I have done this with apricot, plum and peach seeds. I started the seeds last August (2013) and now I have 2 tiny sprouts growing in pots in my window. The other 2 have good roots, so I am hopeful they too will sprout in the next few days. I am planning a hub about the process I used, but have been waiting to get good pics of the growing trees.

IzzyM 2 years ago from UK Author

Excellent idea to have your own photos to hand! I've still got the tree shown above, although it is a lot bigger now. In spring when it's new leaves come through I will update this hub. I've also got several citrus trees - I can't remember if they are oranges or lemons LOL! Good luck with your seedlings :)

I've grown them in Scotland which is pretty far north. I don't have a conservatory but if I did I'd keep them there. At the moment I've still got one in the unheated greenhouse. It looks a bit miserable because it has shed its leaves for the winter, but it's getting big. I left it outdoors last summer and took it in when frosts threatened.

Nanny 6 months ago

I thought I read somewhere to keep them in the dark in the beginning?
