How Much Water To Bring Back Dead Grass. How to fix a dead lawn from a lack of moisture is to simply add more water. Although a length of 2 ½ inches 6 cm is okay 3 inches 8 cm is healthier during summer heat.
Give your lawn time. Water the dead-looking area of grass thoroughly and deeply as soon as possible. Encouraging the dog to consume more liquids as well as quality food will help dilute the urine naturally and ultimately reduce the possibility of lawn burning.
Depending upon the type of soil and its dryness an inch of water should penetrate deep enough into the soil to reach the roots.
How can I protect my lawn when the grass turns brown. If you water adequately to bring it back to life you may need to do a total of about 1 ½ inches of water every week. Consider factors like how much water the grass requires how much of that is provided by rain and how much is provided by your sprinkler system if you have one. As grass loses water its leaves become less rigid and wilt.
