"Don't bag it,"? the catchphrase for leaving grass clippings on your lawn, was coined in the 1980s by Extension horticulturists. Since then, Extension educators have taught thousands of Minnesotans to "green up"? their lawns with fewer pesticides, less water and less work. Decades of turfgrass research by University agronomists backs up Extension's information. Lawn-service businesses and the government benefit, as well. An added bonus is research-based information about composting. Thanks to Extension, Minnesotans are making more informed choices and protecting other natural resources such as lakes and streams by caring responsibly for their lawns and green spaces.
