A "tree ring" is an area approximately the diameter of the limb circle of the tree. This is known as the drip ring of the tree. Mulch this area, you may want to berm it as well. This will help the drip ring hold water better ensuring it reaches the critical feeder roots of an immature, non established tree.
Guy wires/ ties are a good idea as well for young trees given our winds. 3 guys at 120 degrees apart with one of the guys oriented to the northwest (prevailing direction of winds on the front range). A garden store should have webbing straps for guying trees, you want a wide point of contact with the bark. Don't do the dumb thing of running the guy wire through a piece of hose and then going around the trunk. You create a pressure point on the bark and stand the chance of effectively choking that area and above creating a weak point on the trunk.
Keep the drip ring moist but not soaking wet.
It usually takes about 2 years for a 3-4" sapling to become established to the point where wrap and guys are no longer needed.
