That’s “a considerable amount when typical recommendations suggest 2 to 5 pounds of actual nitrogen per 1,000 square feet of lawn annually,” notes Oregon State University’s Extension Service. Sources: Sources: The Lawn Institute, James B. Lawn Clipping NutrientsĪmount mowed off in one growing season (per 1,000 square feet) Leaving the mulch in your lawn returns several pounds of nutrients to your lawn each season. “For example, nitrogen, phosphorus and potassium are all preserved by utilizing the mulch, reducing the need for artificial fertilizers to keep your lawn looking healthy.”
Grass clippings are a natural fertilizer.īy mulching, you reduce your lawn’s fertilizer needs. “Mulching re-introduces essential minerals to your lawn that would otherwise be lost,” O’Rourke said. There are at least five benefits to mulching your grass clippings. If done correctly, it also doesn’t reduce the neat appearance, either.“ 5 benefits of lawn mulching Mulching allows the clippings to revitalize the lawn with nutrients as they decay. “However, it’s not necessarily the best thing. “Bagging is definitely neater because there will be no clumps of grass left over,” said Luke Truetken, owner of Luke’s Landscape & Maintenance of McKinney, Texas. “I would say that the standard has changed over time as people have begun to recognize the nutritional benefit of mulch on their lawns,” O’Rourke said. “Avoiding the bagging of cuttings will help the environment – avoiding the need for this waste material to enter landfills,” said Thomas O’Rourke, of the garden advice site. “Overall, it is better to mulch because the nutrients remain in the soil,” said Teris Pantazes, CEO of the Baltimore-based handyman community site,. So today the norm is “grasscycling” - returning the cut blades of grass right back to the soil. The invention of a new class of mowing blades - mulching blades - let mowers chop the grass blades into finer pieces that are harder to see and decompose more quickly. Turfgrass researchers found that trimmed lawn clippings do not cause thatch. Some research and a bit of technology overcame both of those objections. We thought bagging was better and believed grass clippings contributed to thatch buildup. We also preferred the look of a lawn without the ragged bits of mown grass. In the not-too-distant past, the standard advice was the opposite. Your lawn and the environment will both be happier for it. The verdict is in from gardeners, environmentalists, and scientists: Don’t bag your grass clippings.
