Abstract: A means of injecting tree trunks with preservative fluids comprises using a flexible conduit which is positioned around the trunk covering a slot cut in the trunk. Pumping means pass the fluid under pressure via an inlet and an outlet in the conduit and into the trunk via the slot. The pressure of fluid in the conduit coupled with the flexibility of the conduit effects a seal between the conduit and the slot thereby preventing escape and loss of the fluid.
