I've planted 4 Dunstan Chestnut trees on my 2 acres in Dixie County FL. They are slow growing & I need to keep them fenced because the deer love the leaves, but they are making progress. Got mine from Chestnut Hill Tree Farm in Alachua Fl. Easy to find on google. I'm planting multiples of anything I can think of that deer would like. Whatever grows best, I'll plant more of. Persimmons, peaches, pears, whatever. Lowes & Home Depot sell fruit & nut trees as well - see what grows well in your area & double up.
