Can I prune an espalier apple tree in winter?
Hi. I am new here & not all all the most green fingered person you will ever meet. I have moved into a house recently & the garden has a 2 tier espalier apple tree which seems reasonably well established & bore a lot of healthy apples last year. There are however about 20 or so vertical whippy branches, small diameter but about 3 or 4 feet tall. Is is feasibale to cut these back now, & if so by how much. All help & advice would be very much appreciated
