Bob Vila Radio: Lawn Mower Blade Height

The health of your lawn depends on many factors, including the height at which you set your mower blade to cut.

Whatever type of turf you have in your yard, if you want to keep it looking its best, make sure your mower is set to cut at the right height.

And what, exactly, is the right height? Well, for starters, try following the ‘rule of one third’. The idea is that you shouldn’t more than one third the length of the grass at any one time.

So, if you have, say, Bermuda grass—which is healthiest when kept a little more than an inch high—cut it back once it starts to edge up toward two inches. For fescue or rye, which do best at two to three inches, you’ll want to set your mower height up a couple of notches.

Raising the height a bit is also a good idea whenever the turf is stressed by heat, drought, bugs or other factors. Keeping your lawn trimmed to the right height not only promotes healthy growth, it also helps keep weeds at bay.

Height adjustment on most mowers is easy. Just check your manual.
