Compost vs. Mulch: What’s the Difference?

Compost and mulch are often confused, but they serve different purposes in your landscape. Compost is used to improve the soil and growing conditions for plants, while mulch is primarily placed on top of the soil as a protective and decorative covering. Understanding the difference can help you choose the right material for your lawn, garden, trees, and landscape.

What Is Compost?​

Compost is decomposed organic material used to improve soil. Unlike decorative mulch that generally stays on the surface, compost can be mixed into existing soil or applied around plants to add organic matter and improve soil structure.

Super Soil USA’s Fine Wood Compost is made from finely processed organic wood material. It can help improve moisture retention, soil structure, and growing conditions for gardens, flower beds, trees, shrubs, and other landscape plants.

Think of compost as something that helps build better soil—not simply something used to cover it.

What Is Mulch?

​

Mulch is material placed on top of the soil rather than mixed into it. Wood chips, bark, shredded wood, and decorative colored bark are common types of landscape mulch.

Mulch is primarily used as a surface covering around trees, shrubs, flower beds, and landscaped areas. It can help reduce evaporation, moderate soil temperature, suppress weeds, and give landscaped areas a finished appearance.

Unlike compost, mulch is not primarily intended to improve the soil as a growing medium. Its main job is to protect and cover the soil surface.
