I currently grow two varieties of avocados, 'Choquette' and 'Monroe.'  In 2015, I planted an avocado trial at the Shoreline Farm and behind my House at the Main Street Farm.  I planted, 'Doni', 'Simmonds', 'Catalina', 'Choquette', and 'Monroe.'  Everything died except for 'Choquette' and 'Monroe'.  It's probably for the better, because I would rather not have to pick avocados in the middle of Summer.
