I have half a dozen apple trees that are about 30 years old. They crop quite prolifically but the apples are quite small. The trees are about 10 ft tall and have never been pruned. I'd like to get them to a more manageable size and hope at the same time to increase the size of the apples.
They are Egremont Russet, Golden Delicious and Cox's Orange Pippin plus a couple where the varieties are unknown other than that they are eaters.
Any tips on when and how to prune them would be much appreciated please
