Using Compost as Mulch: Free, Nutrient-Rich, and Effective

Mulch covers soil; compost feeds it. Why not both? Excess compost makes superb mulch—free, nutrient-leaching, weed-suppressing.

Benefits of Compost Mulch

• Zero cost—made from your waste.
• Rain leaches nitrogen and carbon downward, constantly fertilizing.
• Shades out weeds like any mulch.
• Improves soil structure as it incorporates.

How to Apply

• 2–4 inches thick around perennials, extending 12 inches out.
• Replenish monthly during growing season as it works into soil.
• Winter: leave in place to insulate roots.
• Spring: pull back to let sun warm soil.

Compost mulch closes the loop: waste → compost → mulch → soil → plants → waste. Pure garden alchemy.
