How Injections Work
Through Photosynthesis, trees absorb water and nutrients with their roots and then pass it up the trunk in a layer just inside of the bark called the cambium. The water and nutrients are pulled all the way to the tips of the highest branches and leaves. Injections use the Photosynthesis process to systemically draw insecticides, fungicides, fertilizers and also antibiotics all the way through the tree and out to the leaves. The amount of time it will take for the liquid to reach the top of the canopy depends on how tall the tree is and also how well the tree is transpiring, or pulling water and nutrients through the trunk. Once the liquid reaches the canopy, it will remain effective for up to one year.
