The answer to 'difference between mulch and rock' is that mulch and rock are both commonly used landscaping materials, but they serve different purposes and have distinct characteristics. Mulch is an organic material, such as wood chips, bark, or leaves, that is spread on top of soil to suppress weeds, retain moisture, and improve the overall health of plants. Rock, on the other hand, is an inorganic material, such as gravel, stones, or pebbles, that is primarily used for decorative purposes, to create pathways, or to control erosion.
The main benefits of mulch include its ability to insulate the soil, prevent evaporation, and gradually decompose to enrich the soil. Rock, on the other hand, is more durable and long-lasting, and can be used to create a low-maintenance, clean-looking landscape. The cost of mulch and rock can vary depending on the type and quantity needed, but in general, rock is a more expensive option upfront, though it may require less maintenance over time.
