Has anyone ever grown this on M27 rootstocks. I was thinking of planting it as a super colummnar but read that on M27 it does not give a very good crop.
Is this true also what is a good supplier ?
I am a big fan of Keepers Nursery, Maidstone. They'll answer your questions, have a lovely website packed with information about rootstocks etc, and are very nice people. They're easy to Google.
