Grass Clippings, Bag or Recycle?

One question many “home lawn care enthusiast” ask is if mulching grass clipping is beneficial or harmful.

The University of Florida reports that by allowing the grass clipping to drop onto the lawn instead of bagging the grass the yard does get some benefits.

In fact, the UF claims that about 3% nitrogen is contained in the dry weight of grass clippings. Put another way. One hundred pounds of dry grass clippings hold an equal amount of Nitrogen as a 50-pound bag of 6-6-6.

Allowing the cut grass to return to the soil puts valuable nutrients back into the soil. Not only Nitrogen but also other essential elements like Phosphorus, Potassium, Manganese and Iron. Grass clippings quickly decompose. Some “mowers” bag their clipping since they believe the clippings contribute to the build up of thatch.

Fact is, grass clippings contain sugars which stimulate microbes that help with the decomposing of thatch. So keeping grass clippings on the lawn can actually offer benefits.

Another benefit is environmental. There are estimates that we could save 10% of the space in our landfills if we did not bag the grass clippings when mowing our lawn. Plus there is also the time saving factor. Less time mowing – less time bagging.
