Putting too much lime on your lawn can change the soil's pH level from acidic to alkaline. While grass doesn't do well in acidic soils, an alkaline situation can be just as detrimental to its health. Alkaline soil blocks the grass's ability to absorb vital nutrients necessary for survival. If you apply too much lime, you can reverse the effects over a relatively short time by applying commercially available products designed for the purpose or by adding compost to the soil.

You can thicken new grass by using fertilizer, watering it 1 to 1½ inches per week, mowing when it is at an optimal height, and preventing weeds. You should fertilize your grass while you plant the grass seed, or soon afterward. Use an herbicide to prevent weeds or spot spray with herbicide to kill existing weeds.

Your St. Augustine grass might look bad due to cold winter months, drought, pest invasion, or lawn disease. The first step is properly identifying the problem. Once you’ve figured out what’s making your grass look bad, you’ll need to employ the correct treatments. These treatments may include:

• Properly mow your lawn and keep the clippings on the lawn as organic matter.

• Use healthy irrigation techniques.

• Use the right amount of fertilizer.

• Keep up a good, regular maintenance routine.

• Use fungicides.

A soil test can tell you if your yard is experiencing acidic soil conditions, making your lawn limp, weak, and yellow. Raising the pH level by adding lime can improve the yellowing grass situation. However, lime application is only effective if acidic soil is the problem causing the yellowing.
