Abstract: An E-Z Christmas tree waterer (10) to maintain water (12) within a receptacle (14) of a stand (16) having a plurality of holding screws (18), to support a cut trunk (20) of a Christmas tree (22) in an upright position. The waterer waterer (10) comprises a water reservoir (24) having a bottom outlet port (20) and a higher inlet port (28). An elongate conduit (30) has a first end (32) fluidly connected to the bottom outlet port (26) of the water reservoir (24) and a second end (34) extending to the receptacle (14) of the stand (16). A structure (36) is for supporting the water reservoir (24) above the receptacle (14) of the stand (16), so that the water (12) can flow from the water reservoir (24) through the elongate conduit (30) and into the receptacle (14) of the stand (16).
