When using a tree injection system you should...

• A. High pressure to push chemical in
• B. Use low pressure and allow the tree to uptake the chemical
• C. Spray leaves
• D. Inject directly into trunk

Answer: (B)

Tree injection systems work by delivering a small amount of chemical into the tree’s vascular system and letting the tree’s own sap flow carry it to where it’s needed. Using low pressure is essential because it minimizes damage to the tree’s tissues (cambium and xylem) and prevents forcing material out through cracks or bark. This gentle pressure approach relies on the tree’s uptake and transpiration to distribute the chemical systemically, rather than trying to push it in forcefully. Spraying leaves is not how injections work, and while injecting into the trunk is the method, the key idea is to use low pressure so the tree can take up and move the chemical naturally.
