By injecting a tree, we can distribute fertilizers, fungicides, and pesticides directly into the trees transport system. Another way to get the tree these nutrients to trees is through the soil. In this method though, most of substance washes away. There is another option in which spray is applied to the outside of the tree. Spraying is elaborated in the next paragraph. Injecting a tree is a huge advantage to a tree with poor health. By doing this, we can obtain the best results possible. The chemicals are all put directly into the tree, meaning there is no residue that leaks into the surrounding soil. If surrounding plants come into contact with an unfamiliar chemical it could negatively effect them. This method of injecting pesticides is usually more effective than other ways of dealing with disease. Spraying, like stated before, can leave behind chemicals in the soil. Once the soil is contaminated, not only will it hinder the growing ability of your trees and plants, but there is the possibility of an animal or child encountering it. The health risks associated with this contact are not good. As you can see, the injections are the way to go when it comes to everyone’s safety and the overall health of the plant. How we inject. An injection is usually made at the base of the tree where a pre-drilled hole is made. Once the hole is drilled a needle is firmly inserted into the trunk. While turning the handle of the injectoranti clockwise will usually release the device. Once the handle is released, a steady and constant pressure is applied to the tool and the chemical is released. There are different levels of injections in accordance with the type of tree as well as the trunk diameter and bark density. In each case, we are trying to reach the tree's circulatory system so it may spread out to the rest of the body.
