The benefits of applying mulch at a 3-inch depth
- Weed Suppression: A 3-inch layer effectively blocks sunlight, reducing weed germination and growth.
- Moisture Retention: It helps the soil retain moisture by reducing evaporation, ensuring plants stay hydrated longer.
- Temperature Regulation: Mulch insulates the soil, keeping it cooler in summer and warmer in winter, protecting plant roots.
- Erosion Control: A 3-inch depth is substantial enough to reduce soil erosion from rain or wind.
