Tree leaves turning fall colors
Two of my trees (cornus florida, and kwanzan) are beginning to have orange/yellow colors on leaves. Some are brown and get blown by the wind. They were planted in mid-late April. Is this a disease, or is it just leaf scorch? I dug up some of the mulch because cornus floridas don't like mulch at their trunks, and i just pushed it aside. When I did it is it possible it may have dried up a bit? I don't really water it which i penalize myself for. I just don't want these beautiful young trees to die.
