Summer is a time of high activity for pests as well as tree diseases caused by fungi and other organisms. Some problems may be simply aesthetic, while others can be a real threat to tree health and vitality. As such, it is important to have an arborist check your trees to determine the underlying cause.

With the warmer temperatures of summer, it is critical to water your trees and shrubs thoroughly. Applying a 7-10cm layer of mulch, inspecting for pest infestations and scheduling autumn fertilization can also help maintain tree health and vigor.
