Summer Watering Guidelines for Texas Lawns

August 8, 2014 | Lawn Care, posted by Sasha

Many homeowners get nervous when summer rolls around in central Texas because they know the extreme humidity and dry heat can be fatal to their lawns. Keeping your grass properly nourished and watered is essential to helping it stay green well into autumn. Your city or neighborhood may have predetermined watering schedules in place for summer, so be mindful of those as well as you take care of your lawn. The following Texas lawn care tips can help you keep your grass in good shape all summer long.

How Often Should I Water My Lawn?

Watering infrequently and deeply is the key to a healthy Texas lawn.

This technique helps plants grow longer, tougher roots that will allow them to access water throughout the summer even as temperatures rise. Another tip: water early in the morning, when the sun is weakest and the grass has all day to dry. This prevents the water from instantly evaporating and going to waste. Avoid evening watering — a lawn that stays wet overnight is prone to fungal disease. For the full breakdown of when to water, see our guide to the best time to water your lawn.

How Much Water Does Grass Need?

Typically, the average Texas lawn only needs about an inch of water per week, even in the hottest summers. If you’re unsure how long it takes to reach an inch of water, you can put a cup or can in your yard with an inch high marker and then time how long it takes to fill. In general, automatic irrigation systems disperse water at a much quicker rate than hose-end sprinklers. Start with shorter times and add additional time if large areas of damaged or dried-out grass appear. Of course, if there has been significant rainfall recently, you do not need to re-water.

Watering Guidelines for Different Types of Grass

Your yard’s grass type can also affect how much water is necessary for your lawn. Each grass variety has different tolerances for heat and water, so these guidelines are good to keep in mind.

Grass type How often (peak summer) Water per week
St. Augustine 2–3× a week 1–1.5″ (needs the most)
Bermuda 1–2× a week ~1″
Zoysia 1–2× a week ~1″
Buffalo Once a week or less ½–1″ — an occasional soak prevents browning

St. Augustine: This is a common choice for yards, but is rather vulnerable to lawn diseases and pests that Texas summers can bring. It requires a lot of water to stay healthy, which can present a problem if you are in an area with restricted water access.
Bermuda: Bermuda grass is great in the sun and is very resistant to drought. It can grow and thrive even with very little watering. If you live in an especially dry region of Texas, Bermuda grass is a solid choice.
Buffalo: This type of grass is very tolerant of droughts, but it will start to brown later in the summer if it isn’t adequately watered. However, since Buffalo grass is native to Texas, it is rather resilient and can survive through the dry summers.
Zoysia: Another drought-resistant grass, Zoysia can also survive without excessive watering. It will often stay lush even in the shade, staying true to its soft and luxurious texture.

Caring for your Texas lawn in the summer can be tricky, but it need not feel impossible. By sticking to a regular watering schedule that fits your lawn’s needs, you can keep your grass healthy, lush, and green all through the hot season. Just laid new sod?
