Overwatering Your Lawn in Summer Heat


lawn watering during summerSo, it’s summertime. The weather is a solid 100° Fahrenheit. You’re feeling pretty hot inside your house.

Naturally, that makes you feel bad for your precious lawn that’s outside burning in the sun. You decide to leave the sprinkler on to keep them hydrated. However, is this the best thing for your grass?

There are many hazards to overwatering your lawn:

  • Shallow Root System
  • Risk of Fungal Infection
  • Wasting of Water

If you’re wondering how much you should water your lawn here in the North Texas region when it’s scalding hot outside, you’re at just the right place.

Let’s talk about why overwatering is bad for your lawn.

Shallow Root System

By overwatering, you’re damaging the root system of your lawn and making it extremely shallow. This is because the roots don’t have to struggle themselves to reach for water deep into the soil.

Thus, they remain underdeveloped, growing only just beneath the soil’s surface. Many experts agree that letting your lawn get a little thirsty is a great way to keep it strong and resilient against drought and pests.

This might not seem like a good deal simply for the hardiness of your overall root system. But that isn’t the only problem. Shallow roots also render your lawn more susceptible to insect damage.

Risk of Fungal Infection

When you’re overwatering St. Augustine, Zoysia grass, and Bermuda grass, you’re severely increasing the likelihood of fungal infections.

Fungal infections use moisture to reproduce within your soil. If you’re giving the roots more water than they need, especially without proper drainage, fungal infections are inevitable.

Wasting Water

This hazard is pretty obvious. When you’re overwatering plants in the Texas heat, you’re not giving all that water to the lawn.

Even if you’re following an appropriate irrigation schedule, you’re still using more of this resource than necessary. Plus, some level of loss will still occur in the summer heat, even early or late in the day.

Excessive watering risks the upper layers evaporating even before the lower layers are absorbed. Again, this is wasteful and certainly isn’t doing your grass any favors!

How Much Should You Water Your Lawn in North Texas?

The isn’t a single answer that would suit all lawns. But generally, your lawn should remain on the thirstier side.

When you make water scarce like a natural rainfall, you’re forcing the lawn to grow deeper and deeper roots to search for water. Keeping lawns thirsty may seem like a cruel thing to do, but it actually makes your lawn healthier and more resilient.
