New sod turns brown for one of four reasons in North Texas: too little water, too much water, poor contact with the soil, or heat stress before the roots took hold. The good news is that most browning is reversible if you catch it in the first two to three weeks. Here is how to figure out which problem you have and what to do today.
First: is it dead, or just stressed?
Before you panic, do the tug test. Gently pull up on a brown piece of sod.
- If it resists and feels anchored, roots are forming and the grass is likely just stressed. It can recover.
- If it lifts up easily like a loose rug, it has not rooted, and that section is in trouble.
Brown does not always mean dead. Stressed grass often greens back up once you fix the cause.
Cause 1: Too little water (the most common)
This is the number one killer of new sod in DFW. New sod has almost no roots, so it dries out fast, especially in summer. The edges and corners brown first because they dry quickest.
The fix: water more often, in shorter cycles, so the soil under the sod stays consistently moist for the first two weeks, then taper. Full schedule here: how to care for new sod and watering new sod in summer heat.
Cause 2: Too much water
You can also drown new sod. If the ground stays soggy and the sod feels spongy or smells sour, the roots are sitting in water and starving for air. This is common in low spots and in yards with poor drainage on our clay.
The fix: cut back the watering and let the surface dry slightly between cycles. If water pools after every watering or storm, the grade or drainage needs work, which is a prep problem more than a watering one.
Cause 3: Poor soil contact
Sod roots into the soil it is pressed against. If the ground underneath was loose, lumpy, or never rolled, parts of the sod never make real contact, and those parts brown and lift. Air gaps under the sod are a frequent cause of patchy failure.
The fix: press or roll the loose areas back into firm contact and keep them moist. To avoid this from the start, the bed has to be graded and firmed before laying. See preparing North Texas clay soil for sod.
Cause 4: Heat and foot traffic
A stretch of 100 degree days right after install, or kids and dogs walking on sod that has not rooted, will both cause browning. New sod needs 10 to 14 days of light traffic to knit down.
The fix: keep traffic off it, and in extreme heat add a short midday watering cycle to cool and hydrate the surface.
When to call someone
If you have corrected the watering and large sections still lift up loose after three weeks, the issue is usually the soil prep or drainage underneath, not something you did. That is worth a professional look before you replace anything.
We install sod across Carrollton, Plano, Frisco, Dallas, and the rest of DFW, and we are happy to look at a struggling lawn.
