I have just bought two espalier apple trees, from Crown Nursery actually and they very kindly sent pruning instructions with them. They say I should prune the main stem to at least half, but my book says if I prune now and there is a frost it will cause die back....what to do!??

I would wait until late spring, after the threat of silver leaf.

Oh my goodness, I hadn't even heard of that, I will thanks.
