Moisture retention: Mulch helps to retain moisture in the soil by reducing water evaporation from the surface. This means less frequent watering and more consistent soil moisture for plants.
Weed suppression: A layer of mulch helps to suppress the growth of weeds by blocking sunlight and preventing weed seeds from germinating. This reduces the need for hand-weeding or herbicides.
Soil insulation: Mulch acts as an insulator, keeping soil temperatures more stable and protecting plant roots from extreme temperature fluctuations.
Soil improvement: Organic mulches break down over time, adding nutrients to the soil as they decompose. This improves soil structure, promotes healthy microbial activity, and can ultimately lead to healthier plants.
Erosion prevention: Mulch helps to prevent soil erosion by reducing the impact of rainfall on the soil surface.
Aesthetics: Mulch can give a garden a finished, polished look, and can help to highlight plants and other features in the landscape.
