Want to save money, energy, and the environment? Start with your lawn, advises Frank Rossi, associate professor of horticulture and Cornell’s resident turfgrass guru.

“The shorter you mow your lawn, the more work it takes to keep it looking good,” he told Men’s Health magazine in a recent article.

A backyard with grass that’s only 1 inch long needs mowing every five days. But let it grow to 3 inches and your lawn needs tending only twice a month. What’s more, mowing shorter grass can actually weaken its root system, which can lead to drought, pests, weeds and more expenses.

Other tips? Before you get to work, check that your mower’s blades are sharp. Hitting the stems with dull metal requires more energy to make the cut, spiking your fuel bill by 25 to 30 percent.

To save even more, leave grass clippings in your yard. When they decompose, you’ve got free fertilizer, Rossi says.
