Kousa Dogwood leaves turning red
I planted a kousa dogwood in May 13. Was glad it survived late frosts (after leaf buds had appeared) but now the leaves are prematurely turning red. It started at the bottom branches and the color change is gradually creeping toward the top branches. I have read online that this can be caused by a canker, but I cannot find a canker anywhere on the trunk. I'm in Arkansas, and we have had excessive amounts of rain in the past few weeks. The site of this tree is at the top of a small rise, so I don't think drainage may be the issue. However, it may be getting too much sun; a neighbor cut down a tree that was helping to shade mine. I may have to move it to a shadier location but don't want to stress it further.
