Determining the Cause

• Generally, lawns that turn yellow from lack of water retain footprints when you walk across the lawn. You can check out the lawn after doing yardwork to see if there are depressions from your feet. Also, examine the grass blades closely. Water-stressed lawns exhibit grass blade curl. Press your fingers into the first 3 inches of soil to feel if the ground is dry. Once you have determined that your grass's discoloration stems from lack of water, properly water your lawn.
