hi

I posted this question on the Orchard Forum and didn't get an answer so am trying you cold weather gardeners.

I'd like to know if anybody in zone 4/5 has grown dwarf fruit trees like apples or pears in containers successfully? How big would the container have to be? How would it be insulated in the winter (I assume it would have to be somewhat) to give the roots enough protection?

If anybody has done this or has opinions about it, that's be great!
