How Often Should I Mow My Lawn in the San Antonio Summer?

# How Often Should I Mow My Lawn in the San Antonio Summer?

Howdy, folks! Peyton Johnson here from Recover Landscape. If you're like most San Antonians, you've probably looked out at your lawn in the middle of July and wondered, "How often should I *really* be mowing this thing?" It's a fair question, especially with our Texas heat trying its best to turn everything brown. Getting your mowing frequency right in the summer isn't just about keeping things tidy; it's crucial for the health of your grass.

Weekly vs. Bi-Weekly: What's the Deal in the Summer?

This is probably the most common question I get. Should I mow weekly or bi-weekly in the San Antonio summer? For most healthy lawns in our area, especially those with St. Augustine or Bermuda grass, weekly mowing is generally the way to go during the peak growing season, which includes most of our summer.

Now, I know what you're thinking: "Peyton, it's hot out there! Can't I just stretch it to every two weeks?" You *can*, but it often leads to more stress on your lawn. When you let your grass grow too long between mows, you end up cutting off a larger portion of the blade. This is a big no-no, as it can shock the grass, making it more susceptible to disease and heat stress. The general rule of thumb is to never remove more than one-third of the grass blade's height in a single mowing. If you're only mowing every two weeks, especially when the grass is actively growing, you're almost certainly breaking that rule.

However, there are exceptions. If we're in a severe drought, or if your lawn is showing signs of extreme stress (like wilting or significant browning), you might consider reducing mowing frequency or even skipping a mow. But for a generally healthy lawn getting adequate water, weekly is best.

Why Mowing Frequency Changes by Grass Type

Not all grass is created equal, especially when it comes to how fast it grows. Here in San Antonio, we primarily deal with warm-season grasses like St. Augustine and Bermuda. These grasses thrive in the heat, which means they grow faster when it's hot and sunny, demanding more frequent mowing.

How does grass type affect how often I should mow? Different grass types have different growth rates. St. Augustine grass, for example, tends to grow quite vigorously in our summer heat. Bermuda grass can be even more aggressive. Zoysia grass, while less common for full lawns here, generally has a slower growth rate and might tolerate slightly less frequent mowing. Understanding your grass type is the first step to a healthy mowing schedule.

Here's a quick guide for our common San Antonio grasses during the summer:

Mowing Height Rules: St. Augustine vs. Bermuda

Speaking of mowing height, this is another critical factor, especially in the Texas heat. Cutting your grass too short is one of the biggest mistakes you can make.

What's the best mowing height for St. Augustine grass in the summer? For St. Augustine, aim for a height of 2.5 to 3.5 inches. This taller blade provides more shade to the soil, which helps retain moisture and keeps the soil temperature cooler. It also allows the grass to develop a deeper root system, making it more resilient to drought and heat.

And for Bermuda grass, what's the ideal mowing height during our hot summers? Bermuda grass can tolerate a shorter cut than St. Augustine, but in the summer, I still recommend keeping it a bit higher than you might during cooler months. Aim for 1.5 to 2.5 inches. While Bermuda is tough, giving it a little extra height helps it withstand the intense San Antonio sun.

What Happens If You Mow Too Short in the Heat?

This is where a lot of folks run into trouble. What are the consequences of mowing my lawn too short in the San Antonio heat? Mowing too short, often called "scalping," is incredibly damaging. Here's why:

1. Increased Water Loss: Shorter grass blades mean less shade for the soil. This leads to faster evaporation of moisture, meaning you'll have to water more often, and your lawn will dry out quicker.

2. Weed Invasion: Bare or thinly shaded soil is an open invitation for weeds. They love sunlight and will quickly take over if your grass isn't thick enough to compete.

3. Heat Stress and Burn: The grass blades themselves can get scorched by the sun when they're too short. This leads to brown patches and a generally unhealthy appearance.

4. Weakened Root System: When the top of the grass is constantly cut too short, the plant puts all its energy into regrowing blades instead of developing strong, deep roots. Shallow roots make your lawn much more vulnerable to drought and disease.

So, resist the urge to cut it super short thinking it'll save you a mow. It'll cost you more in the long run with watering, weed control, and potentially having to replace sections of your lawn.

When to Skip a Mow

Sometimes, the best thing you can do for your lawn is *not* mow it. When is it okay, or even advisable, to skip a scheduled mowing?

Bag or Mulch Clippings in Summer?

Another common debate! Should I bag my grass clippings or mulch them back into the lawn during the summer? My recommendation, almost always, is to mulch your clippings.

Here's why mulching is a winner, especially in our San Antonio summers:

When should I consider bagging? If your grass is excessively long (meaning you've broken the one-third rule), or if you're dealing with a significant weed problem and want to prevent spreading weed seeds, then bagging might be a better option for that particular mow. Otherwise, let those clippings work for you!

Final Thoughts from Peyton

Taking care of your lawn in the San Antonio summer is a marathon, not a sprint. It requires a little bit of knowledge and consistent effort. Getting your mowing frequency and height right, understanding your grass type, and knowing when to mulch are all key ingredients to a healthy, resilient lawn that can stand up to our Texas heat.
