ABSTRACT:
A Christmas tree irrigation system for supplying water to a tree stand at the base of the Christmas tree. The system includes a tree stand and a spaced-apart reservoir having an electric pump therein which is connected to a conduit leading to a tree stand. The pump is adapted to be actuated by a power source when the water level in the tree stand diminishes to a predetermined level so as to close an electric switch operatively associated with the tree stand.
