RE: apple trees
I recently did some research and choose to plant some apple trees on my property. I planted some that would ripen in early summer, late summer, and late fall. This way I can give them some variety and keep them coming throughout the year.
As for the pollination factor there are several crab apple trees you could use for pollinators. I planted about 30 crab apples for a conservation program on my place. They will really draw in the deer in a few years. They have tree protectors around them, but the deer still browsed them quite a bit this spring.
