ABSTRACT:
An irrigation device, particularly a tree-supporting enclosure and adjacent float reservoir which automatically feeds liquid to the tree-supporting enclosure, as liquid level is depleted. The device is characterized by a pivoted valve housing which is supported in the wall of the float reservoir. A float extends inwardly from the valve housing to engage liquid in the float reservoir. As the liquid is depleted, the float and valve housing are pivoted to open an inlet conduit, thereby feeding additional liquid to the float reservoir.
