A combined root deflector and watering collar which may be assembled from a plurality of panels. Each panel has a preselected shape and is formed of a comparatively thin body member having an upper arcuate edge, a lower arcuate edge and a pair of spaced apart lateral edges extending between the upper and lower arcuate edges. The upper and lower arcuate edges are concentric about a center remotely spaced from the upper and lower arcuate edges. The body has an outer surface of an inner surface and radially extending ribs project from the inner surface between the upper arcuate edge and regions adjacent the lower arcuate edge. A notch in the body at the lower arcuate edge adjacent each of the ribs and a thin section of the body extending along the rib from the notch are provided to achieve a weakening of the body so that as roots of the plant growing through the notch enlarge, the body will tear adjacent to the ribs and starting at the notch. Edge ribs are provided on each lateral edge defining a "T"-shape with the body and extending both from the inner surface and outer surface. A connector having walls defining a cavity for engaging edge ribs is provided so that lateral edges of adjacent panels may be joined together and a plurality of the panels may be thus joined together to define a substantially frusto-conical root deflector and watering collar. The dimensions of the panels are controlled so that the same panel may be used in combinations of, for example three, four and five to define different sized frusto-conical root deflectors and watering collars.
