Are the red tips young or mature? If you move it be sure to dig a wide hole and deep to insure of getting the roots. It would have been best to move it in the fall or winter but if you move it do it now, don't wait another week.

Since the tree is in the ground less than one year it can be treated as a potted specimen. Root prune the tree at about the original pot size by taking a shovel and vertically cutting the soil. Dig a moat outside this cut by digging around not into the cut root ball area. Under cut the root ball and transplant to the new site. Make sure you water the tree before doing any of this and have the new site dug and prepared as you would for planting any new plant.

Great! Thanks for the tips. I just watered it last night really well and will water some more around the area where I'll be digging around it to soften it up a bit.

And just to clarify, I'm moving the young maple, not the mature redtip next to it. They're about 3 feet apart right now and I don't expect to run into the redtip roots when I pull up the maple.
