Definition

Mulch is used in gardening and landscaping to improve soil health, retain moisture, suppress weeds, and enhance the visual appeal of planting beds. It can also help regulate soil temperature and prevent erosion.

Examples of Use

• Gardening: Applying mulch around plants and trees to retain soil moisture and reduce weed growth.
• Landscaping: Using decorative mulch, such as bark or crushed stone, to enhance the appearance of garden beds and pathways.
• Soil enrichment: Incorporating organic mulch, such as compost, into the soil to improve its fertility and structure.

Related Terms

• Ground Cover: Plants or materials used to cover the soil surface in gardens and landscapes.
• Topsoil: The uppermost layer of soil, rich in organic matter and nutrients.

Notes

• Different types of mulch, such as organic (bark, leaves) and inorganic (crushed stone, plastic), offer various benefits and aesthetic options.
• Mulch should be applied at the appropriate thickness to be effective, typically 2-4 inches for most applications.
• Regular replenishment of mulch is necessary as it decomposes or gets displaced over time.
