Why do certain trees appear to be dying?
The causes may be difficult to determine. However, trees may take several years to react to dry conditions. If their natural defenses against insects have been compromised, bark beetles will attack such weakened trees. These insects are usually the last nail in the coffin and are impossible to treat with insecticides. How do I protect my trees and shrubs for the remainder of the summer? If possible, give them a good soaking once a week for the next month or so until the fall rains return. A high water bill may be inexpensive compared to replacing landscape trees and shrubs.
