Mulch is a protective layer spread over the soil. It can be made of organic materials such as straw, grass clippings or wood chips, or inorganic materials such as stone or plastic. Using mulch in your vegetable garden is a smart and effective way to keep your plants healthy and thriving.
Types of Mulch
Straw, grass clippings, wood chips, and compost are essential for vegetable gardens, providing nutrients, improving soil structure, and temporarily tying up nitrogen.
Inorganic Mulch
Plastic Sheeting, Landscape Fabric, and Gravel and Stones are effective for controlling weeds, retaining moisture, and providing pathways and permanent plantings without decomposition or nutrient addition.
How to Apply Mulch
Remove weeds and debris, thoroughly water soil, apply organic mulch 2-4 inches thick, and secure tightly in inorganic mulches like plastic sheeting.
Benefits of Mulching
Mulch helps maintain consistent moisture levels, reducing evaporation from soil surface and promoting healthy plant growth by acting as a barrier.
Weed Suppression
Mulch blocks sunlight, reducing weed seed growth, and reduces competition for nutrients, water, and space due to fewer weeds.
Soil Temperature Regulation
The cooling effect in summer keeps soil cooler, protecting plant roots, while insulation in winter keeps soil warmer during cold months.
Improved Soil Health
Organic mulch decomposes, adding valuable nutrients to the soil and enhancing soil microbial activity, promoting a healthy root environment.
