If you avocado tree is growing from seed it may be many more years before it makes fruit. Read about grafting your tree to assure an edible crop sooner.

If it is a seedling which I suspect it is since it is already 6yrs old, you only have to wait another 2-5 yrs for it to fruit. If you bought a double grafted plant from your local plant shop, it would have fruited after 2yrs. Yes they cost more but are far more reliable. And if you only get 6-8 fruit that first year, it has paid for itself.

Buy a double grafted plant from your local plant shop, it will fruit after 2yrs. Yes they cost more but are far more reliable. And if you only get 6-8 fruit that first year, it has paid for itself. Seedlings are not reliable and will take up to 10yrs to fruit.
