Compost Soil: Uses, Coverage & Calculator
An organic compost blend that improves soil structure, moisture and nutrients in beds and lawns.
What is Compost Soil?
Compost soil is rich in decomposed organic material. Mixed into existing soil, it loosens clay, helps sandy soil hold water and feeds plants as it continues to break down.
It is best used as an amendment or top-dressing rather than on its own. Blends vary, so check the product details for what is delivered in your area.
