Dogwood Tree Dying
It appears that my Dogwood tree might be on the verge of dying. The leaves on the bottom 4/5 of the tree turned gray and after the rain, turned an ugly color of grayish, brownish, with a little red. It took a hit during the ice storms of a couple of years ago. It is around 30+ years old. See attached pics. Is there a county service that will come to my house and take a look?
We viewed your photos. This looks like powdery mildew, a fungal disease on the foliage. There is a range of susceptibility among dogwood to powdery mildew. The best recommendation is to plant powdery mildew resistant varieties in the future. Pruning for air circulation may help. You will have to monitor the plant in the future and decide if you want to spray fungicides or horticultural oil products listed for powdery mildew. This disease does not kill the plant but can weaken it. http://extension.umd.edu/hgic/powdery-mildew-trees-and-shrubs
