How can i get green grass again?
Sounds like a common bermudagrass lawn or similar spreading grass type. The water will help, but it takes a week or so for damage to be mown off. Try some fertilizer–and dont use any weed & feed products if you dont know what type of grass you have. Follow the directions on the bag. For best results, take a chunk of the lawn down to the local garden center and ask them what they think will work best! Good luck on the lawn! Cheers!
