|My tree that is 27 years old grown from a red tip photinia leafed up as always and now all the leaves are falling off and the entire tree's leaves have brown spots aLL over them. What to do? It is a big tree now with shrubs all around it. I could send you a picture.

|Your red tip photinia has developed a common fungal leaf spot. It happens when the spring is wet and the foliage is young and therefore most vulnerable to the disease. Some years are worse than others and if the new growth can grow and mature without rainy weather it usually won't be affected by the fungus. You can spray with a fungicide such as funginex to help control the problem. The fungicide will protect newly emerging leaves but will not fix the affected leaves. They will probably drop off and should be raked up and removed from the garden. New foliage will be healthy if you use a fungicide. Apply according to label directions. Best wishes with your photinia.
