Have you ever grown an avocado from a pit in a glass of water? It's always amazing when something impossible turns out to actually grow in your zone. This is my avocado tree from a seedling. It's probably a Hass avocado since 95% of the market is the Hass variety. This is an 8 year old tree. I've grown all three strains of avocado here in zone 9 Houston and all are tricky. The West Indian strain can take the humidity, but can't take even the slightest frost. The Mexican variety can take hard freezes down to 22, but can't take the relentless summer humidity and mood swings from dry to wet. The Guatemalanstrain can take light freezes, but get stressed with temps over 95! So none can take the Houston combination of hot summers, freezing winters, and endless high humidity. So this avocado tree is quite special to me! I've tried about 20 different seedlings and this is the only one to make it. About 3 years ago, I started looking around town for other Avocado trees and know of 3 or 4 that somehow can grow here. The lesson: don't give up on a plant just because the books say it can't be done. Thanks for visiting 3 for Thursday. Visit Cindy at My Corner of Katy for her latest 3 for Thursday.
