A one-piece molded water chamber in the form of an annulus having a large open segment which permits the chamber to serve as a yoke which can be positioned on the ground surrounding the trunk of small trees at the base of the trunk. The water chamber is made of a strong, semi-rigid material so that the segmental opening can be spread apart to permit it to fit around a tree trunk which may be somewhat larger in diameter than the size of the open segment. The chamber is continuously fed with water from a standard garden hose. The wall of the chamber is pierced with a single row of water orifices which are distributed along a line around the upper, outer diameter of the annular body. This arrangement permits the watering of a tree outward, around the drip-line beneath the tree's outer foliage. In addition, this arrangement also prevents introducing water into the soil around the region immediately surrounding the tree trunk. This watering pattern is specifically intended to prevent disease and decay of growing trees prior to reaching their full-grown state.
