In this guide, we’re going to talk about how often you should water your St. Augustine grass in the summer to keep it happy and healthy.

What is St. Augustine Grass?

St. Augustine grass is a type of lawn grass that is commonly found in the southern United States. It’s known for its thick, lush blades and dark green color. It’s perfect for people who want a beautiful lawn without having to spend hours mowing and maintaining it.

Fun Fact: St. Augustine grass is named after the city of St. Augustine, Florida, where it was first discovered by Spanish explorers in the 1500s!

Why is Watering Important?

Water is like food for your grass. It helps the grass grow and stay healthy. Without enough water, the grass can turn brown and die. So, it’s important to make sure your grass is getting the right amount of water to keep it looking great.

How Much Water Does St. Augustine Grass Need?

In order to thrive, St. Augustine grass requires approximately 1 inch of water per week. This can come from rain or from irrigation (watering with a hose or sprinkler). If you’re using a sprinkler, you’ll want to water your lawn for about 30 minutes to get an inch of water.

When to Water St Augustine Grass?

The best time to water your lawn is early in the morning or in the evening when the temperature is cooler. Watering during the hot part of the day can cause a lot of the water to evaporate before it can soak into the ground.

Also, try to water your lawn deeply and less frequently. This will help the grass develop deeper roots and make it more resistant to heat and drought.

Tips and Tricks to water st Augustine grass in summer

  • You can check if your lawn needs water by walking on it. If it feels spongy, it’s probably getting enough water. If it feels hard, it’s probably time to water.
