This past week, all three Bartlett offices in the Rocky Mountain Division participated in the annual Saluting Branches day of service.

Insects pests can be harmful to trees and shrubs
During spring, pests that have been overwintering in trees and shrubs become active. Some defoliating insects will be hatching soon. Additionally, tiny scale, aphid and mite insects will become active with populations quickly growing to harmful levels. We can provide effective treatments to minimize damage and help prevent a full-blown infestation.
