What Causes Yellow Grass
There are lots of issues that can make a healthy Central Texas lawn change color from green to yellow. Here is what we find most often:

A lack of nutrients in the soil can lead to an unhealthy lawn. This also makes grass susceptible to pests and diseases, which cause the grass blades to turn yellow. In the spring, it’s typically a nitrogen deficiency.
To repair your lawn in spring a lawn expert can often detect the problem without lab-testing the soil’s composition. See some potential solutions below for repairing your lawn this year.
If soil issues caused your yellow lawn, you can amend the soil with compost. This can help fix problems such as poor drainage and proper pH levels.
Adding fertilizer can also help repair a yellow lawn. A good fertilizer product can replace nutrients missing in the soil, such as nitrogen. (For example, Emerald Lawns provides fertilizer treatments throughout the year. We match different fertilizers based on the season, temperature, and your lawn’s unique needs.)
Nitrogen or iron supplements can restore yellow grass to green.
Seasonal changes can lead a lawn to yellow.
Lawn scalping, or cutting the grass too short with a lawnmower, can leave only yellow or brown grass behind. A low mow should only happen that first cut of spring.
In the spring, St. Augustine can suffer disease when temperatures are in constant fluctuation.
Iron deficiency is another cause. Many times, with heavy rains, turf will grow faster than the turf can take up nutrients and causing some grass yellowing, similar to inflating a balloon.
In fall and winter, Bermuda grass can turn especially yellow, because Bermuda is a warm-season grass.
