Abstract: An apparatus and method for injecting liquids directly into the stem or trunk of a plant. The apparatus includes a container for holding liquid, an injection device and a conduit extending between and connected to the container and the injection device. Mounted on the injection device is a tapered, wedged-shaped needle having an outer surface, a liquid-conducting needle conduit and at least one ejector hole extending between the outer surface of the needle and the needle conduit whereby liquid may be transferred from the needle conduit to the outer surface of the needle. Liquid may thus be transferred from the container through the conduit to the injection device, through the needle and out of an ejector hole onto the outer surface of the needle for injection into the stem or trunk of a plant.
