A system and method for the suppression of vegetation growth under fencing and the prevention of premature rotting is presented. The system includes moisture resistant edging blocks configured to rest between the fencing and the ground. The blocks include a lower surface for resting on the ground and an upper surface adjacent to a lower portion of the fence. The system includes a plurality of blocks selectively routed and interlocked together. The blocks may optionally include a notch to permit the full enclosure of the fence post, a groove to permit selective routing of exterior fluid lines and electrical lines along the fence, and a hollowed channel for interlocking neighboring blocks together.
