Are grass clippings beneficial?

When handled properly, grass clippings can provide significant benefits. Because they break down quickly, clippings rapidly release nitrogen, phosphorus, and potassium back into the soil. This is a natural way to fertilize the lawn, and it typically reduces the need to apply synthetic fertilizers by 25-30%. Additionally, clippings improve soil structure, resulting in enhanced water retention and increased microbial activity.

Use efficient mulching practices for the most benefit. The first thing you want to ensure is that your mower uses sharp mulching blades to cut the clippings into small pieces. You will also like to mow your lawn often enough that the length of the clippings is at or below 1 inch in length. I switched to mulching mowers years ago, and I no longer have to bag, which has made my lawn healthier overall.

Debunk myths about clippings. They don't cause thatch; that's from roots and stems. Clippings break down quickly in healthy soil, typically in 7-10 days. Additionally, they won't introduce or spread weeds if they're properly maintained because most weed seeds, when they do occur, develop above the height of mowing.

Modify practices during an outbreak of disease. Collect and remove clippings that indicate symptoms of fungal infections such as brown patch or dollar spot. Instead of composting them, bag these clippings to avoid spreading the pathogen. Once the serious/fatal conditions of the lawn are corrected and it is healthy again, resume mulching.

Sustainable lawn care views clippings as a resource to be utilized, not discarded. It conserves time and money while also conserving environmental resources. Begin to leave clippings this coming season as you witness your lawn flourish with nature's natural fertilizer.
