re: What to do with an avocado tree in Mandeville

I have planted several in Baton Rouge, all died within a few years despite efforts to protect from cold, and various efforts to protect from direct sunlight.

Apparently, until they leaf out really well, the bark is subject to sunburn, best prevented with partial shade (that can be eliminated once the tree gets more mature) and/ or painting the bark with a 50/50 mix of water and a light colored latex paint.

Despite doing all that, mine all gradually died, some lasting 2-3 yrs.

I now have one in a big pot for more than a year that is thriving, and I believe it is because of the loose potting soil allowing prompt drainage. It does not tolerate heavy Clay soil that can stay water logged.

When I get around to planting this one, it will be in the full sun, but I will build an enclosure in which I can buildup soil about a foot tall and 3-5 feet in diameter using mainly sand and compost to maximize drainage around the root ball.

if that does not work, I give up. I have planted Mexicola and all 3 normally available varieties, fantastic, Lila, and Joey. My current one was sold as "Grande"

Once established, I think they are about as cold tolerant as the most cold tolerance citrus
