What is "mulch"?
Mulch is a material, such as wood chips, leaves, straw, or compost, spread over the soil around plants. It helps retain moisture in the soil, regulate temperature, and prevent the growth of weeds. Mulch also slowly breaks down, adding nutrients to the soil. It can improve the appearance of garden beds and protect plants from extreme weather conditions. Depending on the type, mulch can be organic, like bark or straw, or inorganic, like rubber or gravel. It is often used in gardens, flower beds, and around trees.
