We have dwarf fruit trees, but most are only a few of years old and not into heavy production yet. Two that I know of that have been doing especially well, with heavy production are the Ginger Gold apple and an Asian pear.

We use to have a Dwarf Meyers Lemon tree,,, it gave us plenty of lemons... but my hubby kept it pretty well pruned to keep the tree healty.. pretty much easy peasy to grow... unless you over water it and then it will croak! lol!
