Got SWMBO 2 Crimson King Red Maples for Mom's day. Planted them as instructed, watered well and mulched heavily. One tree is OK, the other has constantly dry leaves. The leaves are stiff, not pliable. I'm watering and the soil is wet, but the tree doesn't seem tpo be getting it. Should I dig up arounf the tree and mix in peat moss with the native soil to hold moisture? It is a clay type soil and a relativly dry area. Will the "Wilt-Pruf" type sprays help the leaves hold their woisture or is that stuff just for cut flowers etc?
