ABSTRACT:
A system and method for injecting liquids into trees is provided with an injection device having a liquid container and a removable needle. The system is engaged with a tree so that the needle is disposed into the sapwood of the tree. The liquid is injected into the tree out ejector holes in the needle that are sized to permit the passage of the liquid but to self-seal when engaged by tree fiber. Once the liquid is injected, the injection device may be disengaged from the tree and the needle. The needle may be permanently left in place or removed after a short time.
