Last Spring I planted two apple trees. One is like a three-pronged fork. The middle "prong" (limb) curves sharply, crossing an outer limb. The other tree has sprouted "suckers" at the base. Questions: 1. At what point should I prune that curved limb? At the base where it comes out of the trunk, which would leave a forked tree? 2. Should I prune it leaving some limb? 3. Is now a good time to prune? Also, how do I keep the deer from nibbling the tops of the limbs off? I'm thinking about putting wire cages around the trees (this will also keep my husband from mowing them down like he did my peach trees).
