Q.What Can I Expect Or What Should I Do About An Avocado Tree That I Grew From A Florida Avocado Seed.
In 2007 I took the pit (seed) from a Florida avocado and put it in some water. After the seed sprouted I planted it in our garden. In 2012 we moved and I transplanted the avocado tree to an inside corner of a fence in our villa. The avocado tree is now about 25′ high. A few years ago during a long freeze the avocado tree lost all its branches. However, new growth was fantastic. We have never seen an avocado. This year the tree for the first time had many, many blossoms. However, no avocados and all blossoms are gone. What can I expect from this tree? The tree continuously drops some leaves so if I can not expect any avocados in the near future I may as well cut it down to save all the clean up effort.

If you do not know whether your avocado is a type A or type B, then you may need to have a type B tree around. They will be self-fertile on more occasions, and will pollinate a type A, as well. Here are some articles that will help:
