So my 30 yo avocado lost all it's leaves this past winter in Brazil, and it never came back. Not sure what caused its demise, but I want to plant some new ones. I still have a small avocado about 8 feet tall that I want to top work as it was just a seedling. Because of my heavy rainfall and humidity, I think the Florida avocados would do better in my climate. Can anyone shed some light on this and maybe suggest which cultivars I should graft? My temperatures rarely go below freezing, but it still is possible.
