The answer to 'how does mulch work' is that mulch is a protective layer of material placed on top of soil to improve plant growth and health. Mulch helps retain moisture in the soil, suppress weed growth, moderate soil temperature, and improve the overall appearance of landscaping. Organic mulches like wood chips, bark, or leaves break down over time and add nutrients to the soil, while inorganic mulches like rocks or gravel provide a long-lasting decorative effect.
Using mulch properly is an important part of effective landscaping. Applying a 2-4 inch layer of mulch around plants and trees can provide significant benefits for your garden and yard. Mulch should be kept a few inches away from the base of plants to prevent rot or disease. Regularly replenishing the mulch as it decomposes will ensure your plants continue to thrive.
