Summer in North Texas Is a Lawn's Toughest Test
When temperatures climb above 100°F and rain becomes scarce, your mowing practices can make or break your lawn's health. The way you mow during June, July, and August directly impacts how well your grass handles heat stress, retains moisture, and recovers when cooler weather returns.
For homeowners in Rockwall, Rowlett, Heath, Sunnyvale, Forney, Garland, and Mesquite, here are the mowing best practices that will keep your lawn looking its best through the brutal North Texas summer.
Raise Your Mowing Height
This is the single most important summer mowing adjustment. Taller grass shades the soil, reducing moisture evaporation and keeping root zones cooler.
Bermuda grass: Raise from your spring height of 1.5 inches to 2 to 2.5 inches during peak summer heat. This extra half-inch of blade length makes a significant difference in soil temperature and moisture retention.
St. Augustine: Maintain at 3 to 3.5 inches. St. Augustine naturally grows taller and needs that height to protect its shallow root system from heat stress.
Zoysia: Keep at 2 to 2.5 inches. Zoysia is more heat-tolerant than most grasses but still benefits from slightly taller summer mowing.
The One-Third Rule Matters More in Summer
Never remove more than one-third of the grass blade in a single mowing. In summer, this rule is even more critical because cutting too much at once stresses the plant and exposes the soil to direct sunlight.
If your lawn gets ahead of you — maybe you skipped a week due to vacation — don't try to bring it back to height in one pass. Mow it down gradually over two or three sessions, removing no more than a third each time.
Mow at the Right Time of Day
Best time: Early morning (before 10 AM) or late afternoon (after 5 PM). The grass is less stressed, and the cut surfaces have time to heal before the next day's peak heat.
Worst time: Midday, when temperatures are highest. Mowing during peak heat compounds the stress on already-struggling grass and can cause tip burn on freshly cut blades.
At Go Green Electric, we schedule our routes to service properties during the cooler parts of the day whenever possible. Our electric equipment also runs cooler than gas engines, which means less radiant heat near the turf during mowing.
Keep Your Blades Sharp
Dull mower blades tear grass instead of cutting it cleanly. Torn grass tips turn brown, lose moisture faster, and are more susceptible to disease. In summer, when your lawn is already under heat stress, dull blades can push it over the edge.
We sharpen our mower blades regularly — a practice that's easier to maintain with electric equipment since there's no engine vibration wearing down the cutting edges as quickly.
Leave the Clippings
During summer, grass clippings are your lawn's best friend. They decompose quickly in the heat and return nitrogen and moisture to the soil. A season's worth of clippings can provide up to 25% of your lawn's nitrogen needs.
The only exception is if your lawn is diseased — in that case, bag and remove clippings to prevent spreading the pathogen.
Adjust Your Mowing Frequency
During peak summer heat, grass growth naturally slows down. You may be able to extend your mowing interval slightly — but don't skip weeks entirely. Even slow-growing grass benefits from regular mowing to maintain an even height and remove any weed seed heads.
Our weekly service continues through summer because consistent maintenance prevents the lawn from getting ahead of us and requiring a stress-inducing heavy cut.
Water Smart, Not Just More
Mowing and watering go hand in hand in summer. Water deeply (about 1 inch per week) but infrequently — two to three times per week maximum. Deep, infrequent watering encourages roots to grow deeper, making your lawn more drought-resistant.
Water early in the morning (before 10 AM) to minimize evaporation and give the grass time to dry before evening, which reduces disease risk.
The Go Green Electric Summer Advantage
Our electric mowers are particularly well-suited for summer conditions. They produce zero exhaust emissions — which matters when you're already dealing with ozone alerts and poor air quality during North Texas heat waves. They're also significantly quieter, so early morning service doesn't disturb your household.
