We have a haas avacado tree about 15 feet tall now with avocados on it. We got the plant from a nursery about 3 years ago. We bought it because we were told that if you grow one from an avacado from the store, that it wouldn't bear fruit. However a friend of mine has one she grew from an avocado from the store and it does have fruit on it. SHE was told if it's an organically grown avocado, it WILL bear fruit. Who has had similar experience? Was it an organically grown avocado?
