So, you think you’re on top of your lawn care maintenance, but what happens when you mow your lawn too often? Well, you could be doing more harm than good. Overall, the key to keeping a growing lawn healthy is mowing it according to its growth. If the weather is cool and the growing is minimal, mow less frequently. If it’s during the growing phase, mow more often. Don’t mow the lawn just for the sake of it or on an inflexible schedule.
Most advice for a healthy lawn says to follow the ‘one-third rule’: Never cut more than one-third of the height. “If your grass is growing, you’ll be mowing”. Each grass type looks best and stays healthiest at a certain height. Use your mower to maintain that height as closely as possible. Cutting your lawn too short can be just as damaging as letting it grow too tall. The basic rule of mowing is to never cut more than one-third of the leaf blade.
It’s true that mowing can be unhealthy and even stressful for the lawn, especially if the lawn was cut too short within too short of a time period. In other words, you want to be consistent about mowing, and if you get it too long, you should only cut off 1/3 the next mowing and then gradually reduce the height. Keep in mind that during the warmer months you’ll want to have the grass a little longer to protect the soil from the sun and evaporation. Mowing too often, especially if you remove the grass clippings, runs the risk of depleting nutrients and can increase the build-up of thatch – that spongy layer that can cause issue with the health of the lawn.
