Whether you have newly established landscape plants or stately mature trees and
abundantly flowering shrubs, you have to stay on guard against opportunistic
enemies. Certain insects, mites, and diseases, if not properly controlled, can
weaken your trees and shrubs, making them unattractive and possibly causing
them to die. Fortunately, with extra vigilance and a little preventive care,
you can help reduce these problems and protect your plants' health and beauty.
Here are some insights from the Lawn and Landscape Institute at TruGreen.
