1. They are synthetic

2. They improve soil health

3. They are cost-prohibitive

4. They are often non-renewable

The correct answer is: They improve soil health

Organic materials in landscaping play a vital role in enhancing soil health. When these materials, such as compost, mulch, or organic matter from decomposed plant materials, are added to soil, they bring several benefits. They improve soil structure, increase microbial activity, and enhance the soil's ability to retain moisture and nutrients. This leads to healthier plants that are better able to resist diseases and pests. Furthermore, organic materials contribute to a richer ecosystem in the soil, fostering beneficial organisms like earthworms and bacteria, which are critical for a sustainable gardening environment. The use of organic materials is an essential practice for promoting ecological health in landscaping and gardening.
