A yard covered in tidy stones might look sharp and low-maintenance, but that bargain-bin decision could quietly sabotage every plant in sight. Garden centers stack bags of decorative rock and gravel near the entrance for a reason. The price looks reasonable, the promise of “no more mulching every year” sounds irresistible, and the clean, modern look appeals to anyone who craves order in a flower bed. Rock mulch feels like a one-time purchase that solves a long list of problems. It seems practical. It seems efficient. It seems smart.
Yet that cheap gardening hack—using rock or gravel as mulch around plants—often stresses roots, overheats soil, and creates long-term headaches that cost far more than a few bags of wood chips ever would.
