What is Tree Injection?

Tree injection is used to help control pests and insects on trees. It is applied through soil injections or by a large syringe inserted into the ground where the roots can absorb the nutrients and minerals and push them to the leaves. These injections can manage insects for up to one year.

When should Tree Injection be used?

Depending on insects being treated the insecticide must be applied two to four months before the appearance of insects but can have a one to two-year residual effect. Soil injection is a great method where overspray could be a problem. Ideally, the injection can be applied from early spring through late fall or as long as the ground is not frozen.

How does Tree Injection work?

Tree injection insecticide is systematically translocated when injected into the trunk or root flare of the tree. Its active ingredient is an insecticide that interferes with nerve impulses and disturbs insect behavior. Pests stop feeding, stop reproducing and eventually die. fertilizer is injected below the roots of the surface vegetation to provide the greatest benefit to the somewhat deeper roots of the trees and shrubs.
