Abstract
A device for watering a tree comprises a water container, an inlet to receive water into the container, an inlet valve configured to close the inlet to the container when a water level within the container reaches a maximum water level and open when the water level drops below the maximum water level, a pressure relief mechanism to limit a pressure in the container to a maximum pressure greater than ambient pressure, and one or more outlets to allow water to discharge from the container to apply water to a rootzone of a tree in use.
