Systemic Injections • 713-776-2040

What is Systemic injection and how does it work?
Systemic injection is a type of trunk injection where small amounts of therapeutic chemicals, contained in sealed capsules, are introduced into shallow trunk wounds around the base of a tree. The injected chemicals are then distributed systemically by sap movement within the tree to the branches, leaves, and even roots within a few hours after injection. The chemicals, such as antibiotics, fungicides, insecticides, and mineral nutrients, are added directly into a tree without any contact with the environment.

Urban Tree Decline/Hypoxylon Canker / Anthracnose Fungi
Lack of nutrients is another reason for urban tree decline. In the forest, the leaves and dead branches fall to the ground. They make a layer of organic matter that decomposes and will fertilize the tree naturally. This is called "nutrient recycling". In the urban environment, this layer is cleaned up and discarded. Trees need to be fertilized annually to make up for this loss of nutrients.
