Pruning unmaintained apple tree?
I have two apple trees in my yard. One is young and small, but the other is mature. I'm no expert, but it looks as though it hasn't been pruned in awhile. It seems like all of the apples are growing on the south side of the tree, which makes me think there's not enough light penetrating the tree.
Would you recommend pruning the south side of the tree to help with penetration? How serious of a pruning job should I do? Should I only go for the new growth/small branches or is it OK if I cut through some of the bigger branches? I don't want to do too much and damage the tree or reduce the fruit.
