Hey everyone, didn't see anywhere else to put this so hope you guys can help. I have 3 Kousa dogwoods across the front of the house, the 2 at each end are lovely, dark green and blooming now. The one in the middle, also blooming but not as noticeable because the leaves are a lighter tone of green almost looks sick as if its missing something? All 3 got triple 19 put around them in February so it don't need fertilizer and we've had plenty of rain also; any idea's? Thanks.
