Have just planted some (see my posting re mini-orchard)- no experience as yet-awaiting reply from somebody out there, though all looking healthy so far. Friends have small (ish) dual apple and get very good results. Think they may be better in ground rather than in tubs as I hear that they tend to become unproductive after a few yaers in pots. Ken Muir website has a lot of info but don't know how to include link!
