If Your Grass Looks Brown After Mowing, Here's What's Happening
Mowing your lawn can put your grass under a certain amount of stress. If you find that your lawn looks brown after you've mowed it, there are several key factors
to consider.
One primary issue is the sharpness of your mower blades. Blunt blades can do more harm than good since they tear the grass rather than snipping it cleanly.
Also, mowing too frequently and trimming too closely to the soil doesn’t allow the grass to grow. A general rule is not to remove more than one-third of the grass height at a time.
Leaving behind grass clumps after you mow can suffocate the grass, leading to brown spots. Mowing in dry and
hot weather can make the situation worse, as it
removes moisture.
If your entire lawn has turned a uniform shade of brown,
it may be dormant. Grass goes into this dormant state as a defense mechanism
to conserve water and
essential nutrients.
Fungal issues often manifest as erratic brown spots across your lawn. Specialized fungicides exist for each type of fungal disease, so it’s best to identify the problem
right away.
