Keep Your Lawn Healthy during The Hot Summer

Tips & Tricks to avoid Heat Stress

August 17, 2016

The peak of summer heat is here – can your lawn handle it?

We suggest the following tips and tricks in order to maintain a healthy, intact lawn during the extreme heat of the summer.

REFRAIN FROM CUTTING TOO SHORT

One common mistake made by both homeowners and commercial landscape maintenance companies is cutting a lawn too short. If a lawn is cut too short, it reduces the plants’ ability to produce energy for growth. When cut at the proper height, however, grass develops stronger roots that support more vigorous plants that are more tolerant of stress. Keep in mind that different varieties of grass have different growth habits that directly relate to mowing heights. For example, cool season grass and warm season grass types require somewhat different maintenance techniques. View our 'Proper Mowing Link' to see which cutting height is right for your lawn.

REMEMBER THE “ONE-THIRD” RULE

When deciding on the correct height to cut your grass, it is important to also remember the “one-third” rule: never remove more than one-third of the grass height at one time. By doing so, the lawn is kept cooler because less plant tissue is removed. In fact, cool season grass types actually benefit in the heat of the summer by setting the blade higher. If a lawn is normally cut at 2.5 inches, for example, increasing it to 3 inches in the heat of summer will come with many benefits.

WHEN IN DROUGHT

Avoid mowing the lawn during drought stress. Lawns under such stress are limited in their ability to recover from mowing and can be damaged even more. Instead, mow the grass after a rainfall or after irrigation day. Also, resist mowing wet grass to avoid clumping.

KEEP BLADES SHARP

When grass is cut with a sharp mower blade, the plant will heal faster than when cut with a dull blade. Dull blades will actually tear the plant tissue, not cut it; this torn grass tissue will develop a brown appearance at the surface and may become more susceptible to stress and disease. Sharper blades will prevent a brown appearance and help to prevent further harm to the plant.
