I planted a "Joey" cold-hardy Avocado a couple of years ago and it is doing well here on the Texas Gulf Coast. I have read that you get a better pollination if you plant an "A" pollinator with a "B". There are all sorts of listings of he better known Avocado's on the net as far as A & B. However I have yet to find a listing with the cold-hardy Mexican varieties as to whether they are A or B. I would like to get another avocado tree to plant as a companion to the one I have. Anyone know which category the Joey, Poncho, Brazos Bell, Fantastic avocado's fall into? Thanks.
