Year-Round Mulching for Roses: Benefits Outweigh Risks

Keep the Mulch—It's Good for Roses

Grass clippings and leaf mulch left from winter protection can stay through the growing season in Illinois. They conserve moisture, suppress weeds, and slowly feed the soil.

Management Tips

• Fluff matted mulch with a cultivator to allow water penetration.
• Apply balanced fertilizer (e.g., 13-13-13)—the nitrogen offsets any temporary tie-up from decomposition.
• Add a handful of lime per bush if soil tends acidic.

No Disease Risk

Properly managed mulch does not cause root rot or fungal issues. It keeps roots cool—roses' favorite condition.
