The frame unit assures dead air space therebeneath while allowing container bottoms to rest directly on the ground. Each of the frame units includes a gripping means to enable manual movement in unison of plural plant containers, and each of the frame units includes sealing edge joinder means so that a plurality of frame units can be assembled into a frame array of preselected size wherein a much larger number of plant containers may be supported in operative position.
