You want to get them transplanted while they are still in dormancy. Right about now, if the ground is thawed where you are.

First dig the hole where you intend to put them. Make it bigger than the root ball will be and fairly deep. Have a measuring tape handy and a tarp to put the tree on. Dig the tree, getting as much of the root as you can then measure the rootball and check your hole. You don't want to plant it any deeper than it was growing. Mix some blood and bone meal in with the soil at the bottom of the hole. Drag the tarp to the hole. Plant it and fill it in half way then pour the water to it. When the water sinks into the ground fill it in all the way with soil, leaving a depression in the soil to hold water. Water again. Stake the tree and tie it. A piece of old hose over cord makes a good tie for a tree. For the next 3 weeks keep it wet and it should do fine.

You realize this is not a one person chore, so have help standing by.

Thanks, much appreciated
