Question
Brown Splotches on Dog
I have a white dogwood tree in front of my window facing the west. When I returned from Florida in July, I found the leaves were covered with brown splotches. The local county agricultural department suggested the brown splotches might be caused by the hot sun rays being reflected onto the leaves. It was suggested that I keep the tree watered and not to add fertilizer at this time.
AnswerIt could also be Dogwood anthracnose. The treatment for lack of water and this disease are similar--keep the tree watered. I would water 1 inch of water--place a pan under the tree and turn the sprinkler on and when the pan has 1 inch of water in it stop. Do this every third day for a couple of weeks then once a week I would not fertilize this will put to much stress on the roots. If you have not done so mulch around the tree with not more than 3 inches deep of organic mulch not piled up on the trunk, This will help hold moisture around the roots. Here is a web link to Dogwood Anthracnose.
