can anyone suggest varieties and where i can get 'patio bushes of some traditional apples?
The October issues of GW has a big feature on apples covering all this.
Try Adams Apples (google) I bought some very old and local apple trees - huge range. However I would say some of the older varieties have fallenout of favour because they are not very good! Considering adding a Bramley etc as some of the very old just don't perform.
