    Can I grow an avocado plant from an avocado stone and what is the best way of going about this?

    Do I need to break the hard outer shell which I imagine contains the seed inside?

    I do not have a greenhouse.

    Good morning, martyn, and welcome to GC.

    I have grown an Avocado (Persea Americana) from a stone ...

    [​IMG]

    This one is 2/3 years old now and about 80cm tall and for some reason sent up two stems! You can just suspend a stone (fattest end downwards) in an eggcup with water covering the base of the stone and sit it in a sunny windowsill. I actually just stuck mine in a shady spot outside where I keep houseplants and the soil is kept moist. You could nick the stone at the base to perhaps speed up the process.

    I am not growing mine in ideal conditions as they prefer moisture ... but mine seems healthy enough, which is what counts. [​IMG]

    Good luck and enjoy the forum.

    [​IMG] Hi Martyn,

    It is important to use a stone from an Organic Hass avocado.. Allot of supermarket ones will not germinate..!!!


    [​IMG] I have one growing in the greenhouse at the moment. It is about 18 month old now & stands between 2&3ft (will try & remember to take a pic tomorrow..) :rolleyes: They obviously grow better in the warmer climes... Like where our LoL is. Mine is doing ok really.. I grew it in compost start to finish using this link..

    Don't forget to have the pointier end upwards.

    hi all
    i registered just now so i could seek help on the same topic!

    my wife potted a random supermarket avocado seed three years ago (for fun) and it has done very well, until now.

    its almost 7 feet tall, still indoors, in a 20'' pot. we realise now that we probably allowed it to grow too tall as its a tall skinny looking thing. it has been replanted into bigger pots on a few occasions but only with compost.

    recently the leaves have started dying and we're wondering if some sort of drastic intervention is required. the trunk looks ok, and there are always some new branches sprouting. maybe its indoor life has expired, or a complete soil change is required. maybe a certain food? is cutting down the truck substantially an option at this stage?

    to be honest i am not even sure what questions i should be asking!
    maybe someone has some experience to share?

    thanks

    Sorry Bry can't help but there will be someone who can. I like your wife love experimenting. the best one I ever did was find a cherry tom gone a bit worse for the wear so to speak at the back of the fridge. I took Out all the seeds and let them dry out. I planted them in the spring and got 12 tomato plants. I had to give loads away to family and friends and they all had a great harvest. Me too.Thats what does it for me. (gardening that is) good luck Bry, they're a great bunch on here ,someone will give you the help you require.

    Brian, home grown avos do only have a limited life but you can try repotting, prune the top down to where the leaves are not dying and add a small amount of general feed. Before the leaves started dying did they go brown or yellow? If brown then the soil was too dry and if yellow the soil was too wet.

    Tips with growing avos:

    MF is right - it is best nowadays to only try growing organic ones. Most of the others are now irradiated before packing in order to lengthen shelf life. Haas is a good one to grow and originated in Guatemala.

    For pot grown ones, they need to be top-pruned before they get 12 inches high and then prune further growth whenever it has grown 6 inches. This gives it a sturdy trunk and a bushier form. If you don't prune then it will grow tall and spindly and a pot grown tree won't survive so long and won't look so good.

    If you are thinking of trying to grow fruit then you will need at least another plant (for pollination) and it will need lots of light and a temperature that doesn't drop below the mid 50's. A heated conservatory is probably a minimum requirement.

    Growing them the way LoL said (suspended in water) is the best way but it can take up to three months to root and sprout. When you put it into soil you need to have the top inch above the surface.

    Keep moist but don't overwater.

    Good luck :)



    That's what comes from sitting in front of a computer for too long. :D

    My Avacado plant (from supermaket fruit) grew to about 2 feet last year but I left it outside during winter. After noting that the plant appeared to be dead I emptied the pot to find that the stone was throwing up two new shoots - now 6 inches high and I shall try to follow the pruning technique as written.
    Funny things are plants..................

    Avocados can take a lotmore cold than it is let out, and it is a goodthing to "mistreat them a bit" in winter, keeeping them rather cool and try. This encourages them to become woody and tough, instead of promoting that long spindly growth typical with homegrown ones.
    My four ys old avocado is just 60 cm tall, with a very thinck barky strem and a tree shaped top.

    I find you can stick the seeds in the ground or water in whichever way and they always do their thing, unless treated to prevent germination.

    I have got three avocado stones sitting in a row in a pot of Holy basil that I grow on the windowsill.
    So far they have nto done much but then they have only been sat there for 2 weeks.
    I will bury them in the soil a bit deeper then I have, keep it moist and see if anything appears.

    There again they might have been irradicated or irridated or whatever it is they do to them to turn them into aliens and maybe nothing will come of it.:)

    Half the fun is trying to see if something will sprout though.
