Mulch is really good for the garden. It’s any material placed on top of soil to cover and protect it, improve soil structure and fertility, and enhance the area’s overall appearance. Mulching mimics the natural environment found in forests where leaves and branches blanket the soil surface, replenishing nutrients as they decompose and creating an ideal environment for root growth.
What does mulch do? A lot of different things including:
- Conserves moisture by slowing evaporation
- Moderates soil temperature
- Impedes growth of weeds
- Helps reduce erosion
- Adds organic matter as it breaks down
- Improves soil structure, fertility, and aeration
- Increases water absorption and retention
- Prevents soil compaction by reducing foot and vehicle traffic
- Makes surface areas more attractive
