Tips for Thinning Your Lawn for the Summer

Protect your lawn against the high heat through these hacks during the summer.



Many Americans consider having a lush, verdant lawn to be a fundamental part of the ideal home. A lush green lawn improves the experience of spending time in the great outdoors, whether for a family barbecue or a game of touch football with friends. But what do you do when scorching temperatures threaten your lawn?

A lawn needs to be able to withstand the usual seasonal heat, sudden heat waves, and the heat brought on by a drought. Methods and approaches to countering these dangers will be discussed.

Keeping Cool When the Temperatures Soar

Temperature changes across the globe are a function of each region’s unique seasons. That’s why you need to make sure you’re planting grass seeds of the right kind for your region. Overseeding your lawn with a heat-resistant variety may help it survive the summer months. The best way to help your lawn survive the summer heat is to mow it frequently, cutting no more than a third of the grass blades at a time. If you want clean cuts, avoid mowing when the sun is at its hottest, and use a sharp blade.

Think about the stress that is put on your lawn as well. A bald area should be treated and reseeded as soon as possible after discovery. These problems are much simpler to address when they are less widespread. By blocking the sunlight and creating a microclimate that weeds can’t survive in, new grass growth is a great way to keep those bare spots looking great.

Sudden, Extreme Heat

Even though temperatures rise and fall with the seasons, an unexpected heat wave presents a different danger and necessitates more preparation. In extreme heat, you may need to water your lawn more frequently; however, you should always water strategically. Water the lawn first thing in the morning so it can soak up the water before the heat of the day causes it to evaporate.

Have no fear if your grass suddenly turns brown. Northern and mountainous areas are home to “cool season grass,” which goes dormant in extreme heat but quickly recovers when temperatures drop. Some homeowners can’t help but over-water or over-fertilize their lawns in an effort to revive it. A second set of issues arises from this, as the salt content of many fertilizers can “burn” the lawn or absorb necessary moisture. Wait until the heat wave is over before applying any chemicals, such as fertilizer or herbicide.

High temperatures and dry conditions

Lawns are especially vulnerable to the double whammy of high temperatures and drought, which frequently plague the South and Southwest. Drought-tolerant grass seed is a necessity there. In order to survive dry periods, these grasses either go dormant or develop deeper roots and wider rhizomes.

Watering restrictions are commonplace during droughts. The best way to water is deeply but infrequently. Deeper watering prevents quick evaporation and promotes stronger roots, which will shield the grass from future heat waves. The longer grass will shade the ground and help retain moisture if you only mow occasionally during a drought.
