In tree injection systems, the pressure setting should be

• A. Use high pressure to ensure uptake
• B. Use low pressure to allow uptake
• C. Use medium pressure
• D. Block the injection

Answer: (B)

For tree injections, the liquids move into the tree through the vascular system, and uptake relies on letting the solution enter gradually rather than forcing it in. Using a low pressure is the best approach because it minimizes tissue damage to the bark and cambium and aligns with the tree’s natural uptake and transpiration-driven flow, allowing the material to distribute through the xylem to where it’s needed. If pressure is too high, it can rupture tissues, cause leaks at the injection site, and reduce the tree’s ability to take up the solution properly. Medium pressure isn’t necessary and still carries risk of tissue injury, while blocking the injection would prevent any uptake at all.
