How Tall Should My Grass Be?

The height of your grass after cutting actually matters when planning for the long-term health of your lawn. A scalped lawn mowed too short can actually stress grass, and open it up to sun damage, diseases and pests, all of which can wreak havoc on the curb appeal of your home. The average lawn is made up of a blend of several grass seed varieties, and while pure seed lawns containing only one variety of grass may vary in their needs, the average lawn will benefit from a mowing height of 1  1/2 – 2 inches tall after cutting.  This is the average desirable height for fall, spring, and winter.

Summer mowing height should be adjusted up, to protect lawns from sun scorching, and drying out too quickly, which can contribute to summer dormancy in many varieties of grass. An average post-mowing height in the summer should range between 3-4 inches, to reduce stress on grass blades, and to provide more shade for the root system and soil, so that both the plant and the soil can retain their moisture better.

Remember this fall to adjust your mower back down to a lower height for shorter mowing, and mark your calandar in late May to change your mowing setting again to a taller height for the summer heat – your lawn will thank you for it!
