Last question in my tree/shrub trouble series- my burning bushes. I have 4 along the side of my house in my flower bed. They are only about 3-4 years old, and this year they really got big compared to previous growth. However, in the past week I have noticed red spots on the leaves, with red tips on some of the newer leaves. Some of the leaves have started to turn red and fall off. This seems to be similar to what is happening to the serviceberry in the back of the house. The burning bushes face the west (the trees face north), and the flower bed they are in is in between the house and the driveway. The soil is very hard and compacted. They have a very thin layer of mulch around them (trees in back do not have mulch around them). Thanks for your help in identifying the potential tree/shrub problems and hopefully what can be done if it will harm the trees/shrubs!
