To all and to anyone. Go ahead and prune your avocado trees as much as you wish. the plants that you have propagated from seed will never bear fruit. if for some reason they do bear fruit, the fruit is highly unlikely to resemble the quality of the original fruit.
if you wish to own a tree that bears fruit go to Home Depot and for the low price of 23.95 buy a Hass avocado. These trees will usually bear fruit within a year.
