Straw mulch is made from wheat, oat, or rye straw — the dried stalks left after grain harvest. It's a lightweight, low-cost option primarily used in vegetable gardens, new lawn seeding, and erosion control on freshly graded slopes. Straw mulch breaks down in a single season, adding organic matter to the soil.

Installation Tips for Indianapolis
Getting the most from your Straw Mulch
- Always buy straw (not hay) — hay contains grass seeds that will sprout
- Spread 2–3 inches deep in vegetable beds; thin to 1 inch over new grass seed
- Water the straw after spreading to help it settle and stay in place
- Work decomposed straw into the soil at season's end as a soil amendment
