RE: apple trees
There is a good article in Quality Whitetails December 04 magazine. The top 6 they mention are:
Honeycrisp
Liberty
Honeygold
Enterprise
Jonafree
Empire
They also mentioned that the rootstock used should be M7 or M111. Not sure what that exactly means but it has something to do with the being a stronger root system and are in the semi-dwarf class.
