Best bet is a Winter Mexican, Lula or Day on a Lula rootstock. You have virtually no chance with any of the Cailfornia types that are grafted onto Mexican or other rootstock.

It's usually best to start them where they will get afternoon shade and let them grow up into more sun. Usually, they flower just when we get our worst frosts, and that puts the kabosh to any crop. So far, I have only heard of two trees that fruited consistently here in the Valley, both seedlings of Mexican type, and I haven't heard any crowing from their owners since the big frost of 2006! I've never tried the ones recommended by rockmaker, so they're probably at least worth a try.

Wish I had room, now!

Thanks guys. The Lula variety looks like it could work.

I may try a couple in pots so I can move them into more protected areas in the summer. Call me stuborn, but we love avacados, and I'm not ready to give up on this idea just yet.
