How to Keep Your Grass Green in the Heat

Summer’s high heat and dryness are death to your lawn. If you live in warm, dry climates, your struggles to maintain a lush, green lawn practically double. Luckily, there are several concrete lawn care tips that experienced landscapers and lawn specialists recommend to help preserve your healthy, green grass during summer’s inevitable heat spells.

Cultivate Longer Grass

Keep longer grass during summer or during periods of intense heat. Longer grass and turf has deeper root systems that access water further down in the ground. Deeper root systems and dense turf tend to keep weeds at bay and prevent them from competing for water. An optimal summer grass blade height is 4 inches, according to HGTV.com.

Maintain Sharp Mower Blades

Keeping your grass long entails cutting it to precise specifications. To do this job effectively, you’ll need sharp mower blades. Dull blades tend to shred your grass, which places even more stress on it, allowing moisture to seep out and weeds to acquire purchase. Shredded grass tips quickly turn brown, filling your lawn with unsightly, discolored patches.

After sharpening your mower blades, be sure to set them at the highest settings on your mower.

Mow Less Frequently, Early Morning or Sunset

Mow your lawn shortly before or after breakfast, or just before sundown. In the mornings, your cut grass retains moisture from dew and has time to repair itself before the daily scorching sets in. During summer’s height, the sun rises fast and reigns for hours, often brutally. Freshly cut grass is extremely fragile and more likely to sustain damage in the noonday sun.

Although mowing at sunset is advisable, your proximity to neighbors might prohibit this activity. Mowers are rather noisy, as you know, and some neighbors might object. Play it by ear.

Water Generously But Infrequently

Your thirsty lawn needs at least 1 inch of water weekly to retain its pristine, healthy, green appearance throughout the long, hot summer. However, it’s better to deliver this amount in fewer feedings and as early in the morning as possible, states the gardening goods specialist Gertens.

Watering infrequently for longer periods encourages the root system to grow deeper and to strengthen. Watering in the morning allows the water to soak into the earth without the risk of quick evaporation in the harsh noonday sun. Skip the nighttime watering sessions, since nighttime watering is conducive to the spread of fungus and disease.

Avoid Walking On Your Lawn

There’s a good reason for the “Don’t Walk On The Grass” signs you see scattered throughout landscaped private and corporate turfs. Walking and hosting on your grass essentially beats it down. Even lush, moist grass takes a minute to bounce back from being walked on.

Dry grass tends to become deformed, losing its shape and appearing limp and sickly. Foot traffic also compacts soil, especially wet soil, which prevents proper soil aeration and exposure of roots to oxygen, according to Scotts Miracle-Gro.

Fertilize and Overseed

Before fertilizing, submit your soil for testing to gauge deficiencies. If fertilizers are necessary, opt for organic, slow-release fertilizers. They won’t burn, and they treat your lawn and its root system to an array of nutrients and fortifiers over a timely period.

At summer’s end or in the fall, consider overseeding your lawn with a grass that is bred to withstand drought and heat. The reinforcement fills in any gaps, improving the sight and texture of your lawn, and compensates for any existing grass that might be prone to heat stress.

Keeping your grass green in the heat is easier than it sounds. By stepping up your care regimen, scheduling your mowing and feeding, and restricting most of your care to the early morning hours, you can enjoy a summer lawn that is verdant and thick on the hottest days as well as throughout any periods of record aridity.
