⚡ CalcWolf Insight

Landscape fabric under rock seems like a good idea, but most professionals skip it. It degrades within 3-5 years, prevents organic matter from enriching the soil, and becomes an ugly mess when exposed. Use 4 inches of rock directly on graded soil — weeds that do grow pull out easily from loose rock.
