What is a septum used for during tree injection treatments?

A septum is a critical component used to facilitate the injection of materials during tree injection treatments. It serves as a barrier that allows substances, such as nutrients or pesticides, to be injected directly into the tree's vascular system while minimizing exposure to external contaminants. The design of the septum typically includes a self-sealing feature that closes once the injection needle is removed, preventing leakage and helping to maintain the integrity of the injection site.

This method enhances the efficiency and effectiveness of treatments by ensuring that the active ingredients are delivered precisely where they are needed, directly into the tree's tissue. By using a septum, arborists can improve the uptake of the injected materials, which can lead to better health for the tree or effective pest and disease management. The focus on the injection mechanism highlights the importance of direct application in tree care practices.
