Michael,

This rainy summer season has brought on many leaf spots and in some cases some leaf blight disease. This is generally not a cause for alarm and the plant will recover and be fine. However if your tree is suffering from soggy wet soil the roots can't get oxygen and will start to die leading to all sorts of problems including death of the tree. Take care to not keep the soil soggy wet. Don't overfertilize and don't use a weed control product around the tree, including turf weed and feeds. These can wash into the root zone if over applied prior to a rain and do some damage to the tree. Unless you tree is a new plant (less than a year old) I suspect it will recover in time be fine and I would not prescribe any care other than to maintain even soil moisture.

Thanks for the question. Please stop in again soon!
