As people become more concerned over the use of pesticides and their effect on the environment, tree trunk injections have become a popular alternative.
Injections are considered more environmentally friendly because they do not require spraying or soil treatments to treat insect infestations and diseases. The chemicals are targeted to a specific area, which keeps the chemicals away from wildlife, people and non-targeted insects. The applications system is simple and can be performed under many weather conditions, including rain and wind.
Drilling injections can wound trees. A tree's health can be compromised by air invading the sapwood or by the drilling process itself, which can damage the vascular system and interrupt the flow of nutrients through the tree. Repeated drillings can cause permanent damage and affect the overall health and life of the tree.
A no-drill procedure minimizes the damage while still remaining effective against infectious insects. In a no-drill procedure, chemicals are injected under the bark and into the cambial zone without introducing air into the sapwood or damaging the tree's vascular system.
During no-drill injections, the chemicals that are injected are moved through the sap upward into the leaves and shoots. Care needs to be taken to inject the chemicals into the tree's water conducting system, which is in the outermost one or two rings of the tree trunk.
If the chemicals are inserted too deeply, then the they will be placed in the inner rings and stay there instead of moving through the tree and doing the job that was intended. Because of the precision necessary to correctly inject the tree, this is a procedure that should be handled by professionals, such as your local tree service.
It takes years for trees to reach maturity, so it is important that we protect them in every way that we can possibly. It's necessary to properly treat them when they come became diseased or invaded by insects that can destroy them. Have your local tree service evaluate your tree if you suspect a problem and make sure that they offer no-drill injections as a form of treatment.
Trees not only provide shade, homes for wildlife and beauty for your surroundings, but they are also environmentally important. They help control pollution and improve the air that we breathe. Take the time to pay attention to your trees and keep an eye out for any signs of illness so they can be deal with before they cause extensive damage.
