Abstract: A device for watering a Christmas tree at its base with a fluid such as water. The device comprises a unitary, molded, generally spherical receptacle having a top pole and an opposing bottom pole, and comprising an open-top, hollow, half spherical bottom having a top lip, the bottom comprising a reservoir for receiving fluid, and having a drainage outlet substantially at the bottom pole, and a half spherical lid having a lower perimeter that matches the top lip of the bottom, the lid hinged to the bottom by a molded, living hinge. The lid may be closed against the bottom so that the lid completely covers the open top of the bottom. There is a molded structure at the top pole, for removably attaching the device to one or more of the tree branches, and a conduit for transferring fluid said fluid from the reservoir to the tree base.
