Our two Norway Maples and one Crimson King Maple all have peeling bark at the base of the trunk. What is the reason for that and what can we do to remedy the situation?

Jerry - take several photos - one of each tree top to bottom (so the Master Gardeners can see if the crown is affected) and then some of the area that is peeling. Also have some photos of the base of the trees. You can email them or bring them to the DuPage office: 1100 E.
