What to Do With Your Lawn in July and August in San Antonio

Hey folks, Peyton here from Recover Landscape. July and August in San Antonio mean one thing for our lawns: heat, and lots of it! It's a tough time for our grass, but with a little know-how, we can help it survive and even thrive. I'm going to share my best tips for keeping your lawn looking good when the Texas sun is really beating down.

Mowing Right for the Heat

How often should I mow my lawn in July and August in San Antonio?

During the peak summer months, your lawn's growth naturally slows down due to the intense heat. Mowing too frequently can stress it out even more. I recommend aiming for once every 7-10 days, or even less if you notice your grass isn't growing much. The key is to never remove more than one-third of the grass blade at a time.

What's the best mowing height for my San Antonio lawn during summer?

This is crucial! For St. Augustine and Bermuda grass, which are common here, you want to set your mower blades higher than usual. I tell my clients to aim for 3-4 inches for St. Augustine and 2-3 inches for Bermuda. Taller grass provides more shade for the soil, keeping it cooler and helping to retain moisture. It also encourages deeper root growth, making your lawn more resilient to drought and heat.

Watering Wisely: It's All About Timing and Amount

What's the best time to water my lawn in San Antonio during July and August?

Early morning is always the best time. I'm talking between 4 AM and 8 AM. This gives the water a chance to soak deep into the soil before the sun gets too high and evaporates it. Watering in the evening can leave moisture on the grass blades overnight, which can invite fungal diseases. We definitely don't want that!

How much water does my lawn need in San Antonio's summer heat?

Most lawns need about 1 inch of water per week, either from rain or irrigation. Instead of frequent, shallow watering, I always recommend deep and infrequent watering. This encourages those deep roots we talked about. You can use a rain gauge or a tuna can to measure how long it takes your sprinkler to deliver an inch of water. It might surprise you how long it actually takes!

What if San Antonio has drought restrictions? How do I keep my lawn alive?

Drought restrictions are a reality here, and we've got to abide by them. Focus your watering efforts on the early morning hours on your designated watering days. If hand-watering is allowed, use it for stressed areas. Consider using soaker hoses for targeted watering, which are often exempt from certain restrictions. The goal is to keep the crown of the grass alive, even if it means the lawn looks a little less vibrant.

Battling Pests and Stress

How can I spot chinch bugs early in my San Antonio lawn?

Chinch bugs are tiny, but they can do a lot of damage. Look for irregular patches of grass that turn yellow, then brown, even when you're watering. These patches often appear in the hottest, sunniest areas of your lawn. Get down on your hands and knees and part the grass at the edge of a damaged area. If you see tiny, reddish-black bugs with white wings, you've got chinch bugs. Catching them early is key to saving your lawn.

Should I fertilize my lawn in peak San Antonio summer?

Absolutely not! This is one of the biggest mistakes I see folks make. Fertilizing in July and August can actually burn your lawn and cause more stress. Your grass is already working hard to survive the heat; adding a bunch of nutrients just makes it work harder. Save the heavy feeding for fall when temperatures cool down.

What should I do if my lawn goes dormant in the summer heat?

It's natural for some grass types, especially Bermuda, to go dormant during extreme heat and drought. Don't panic! A dormant lawn isn't a dead lawn. It's just conserving energy. Continue to water it minimally to keep the crowns alive, maybe half an inch every two weeks. Once temperatures drop and we get some rain, it should green right back up. Resist the urge to overwater or fertilize, as that can do more harm than good.

Mid-Summer Lawn Care Checklist

Here's a quick rundown of what to focus on during July and August to keep your San Antonio lawn in the best shape possible:

What NOT to Do in Peak Heat

Beyond what to do, it's just as important to know what to avoid. Don't scalp your lawn by mowing too short. Don't overwater, thinking more is better – it can lead to shallow roots and disease. And as I mentioned, definitely don't fertilize. Also, try to avoid heavy foot traffic on stressed, dry grass, as it can cause further damage.

Taking care of your lawn in the San Antonio summer is a marathon, not a sprint. It requires patience and understanding of what your grass needs to survive these brutal months. If you follow these tips, you'll give your lawn the best chance to bounce back strong in the fall.
