How Can You Decrease The Risk Of Dehydration?

If the grass is healthy and dark green, very little water is required. If you live in a dry region, or are experiencing drought, you should water enough so that your grass maintains a healthy green color. 

You can decrease the risk of dehydration by increasing the cutting height, by always cutting with sharp blades, by aerating the grass and by mulching your lawn.

A sign of dehydration is the grass turning light green, and then starting to turn yellow.
