here's something nobody tells you before you plant an avocado tree:
most of them never produce a single piece of fruit. not because avocados are difficult, but because there are three things that go wrong almost every time - wrong variety for your climate, drainage that isn't good enough, and a total misunderstanding of how avocado pollination actually works.
(the pollination thing especially. avocados have what's called a Type A and Type B flowering system, and if you don't know about this going in, you can do everything else right and still end up with a beautiful tree that just... sits there.)
i've just published a full beginner's guide to growing avocados at home - covering variety selection, planting, drainage setup, pollination, and how to protect your tree from Phytophthora root rot, which is the thing that quietly kills more avocado trees than anything else and usually isn't noticed until it's too late.
if you've ever wanted to grow your own avocados - or you already have a tree that isn't performing - this one's for you.
