Yes you can transplant trees next spring as soon as extreme weather is over but at least slightly before trees begin to bud out for best results.

Yes, you can grow trees and move them later to get quicker results than starting with new trees but you'd be better off mail ordering bare root trees from a nursery that specializes in hardy fruit trees, preferably located in your region. If you have light soil (more work with heavier soil) you can plant the trees right in the ground and move them bare root when ready to go in permanent locations. I move mature but small (not more than 3 inch diameter trunks) fruit trees all the time).

I would move them now if you know where you want them to be. Tree roots put on some growth in the fall and early winter. If you move them now, that growth will help them get established. If you move them in the spring, some of that new growth may be lost or damaged.

I like fall planting also but in very cold climates it can be risky- or so I'm told.

thank you very much!
