The answer to 'mulch vs rock' is that both mulch and rock can be effective landscaping materials, but they have different features, benefits, costs, and use cases. Mulch is an organic material made from decomposed plant matter, while rock is a non-organic material like gravel or stones.
Mulch provides more benefits for plant growth, such as retaining moisture, suppressing weeds, and improving soil health over time as it decomposes. Rock is more durable, requires less maintenance, and can create a clean, modern look. The choice between mulch and rock will depend on your specific landscaping needs, budget, and aesthetic preferences.
