What happened? This is Southern Florida. Just point a seed at the ground and it sprouts roots.

I neglected it and it didn't rain for months. I read that you shouldn't water avocados much during the winter months here, but I didn't water it at all and I think that killed it. (I'm a dork)

No love. It left :>( Try again, If at first you don't succeed... It could have been other things too. They get bugs that love their leaves.
