espalier apple trees
Hi is there anyone who can offer some advice on rootstock?. I have a new allotment and am looking to plant apple trees - for those with growing experience what have they found to be is best rootstock for espaliers ? ( I am in the north of england) I have a tall fence to grow them against but the fence posts face into the allotment , with the flat side facing out to the park, will it be okay to plant espalier that will not be flat against fence ? due to fence posts or would it be better to do cordons and if so what do people think it the best rootstock. Please note there is hedging along the other side of the fence, thanks !
