A Common concern all homeowners have, why is my lawn turning brown? It my law dead? The answer is no. Your lawn is sleeping also known as dormant. This process of protection normally occurs in the winter, but can also occur in the summer.
Over watering your lawn causes more damage than lack of water. That is because most turf grasses can handle dry spells but not flooding. Most grasses require 1-1.5 inches of water per week. This is enough water to moisten the soil to 4-6 inches below the surface for clay soils and 8/10 inches for sandy soils.
Do not guess at how much water your lawn is getting. For measuring Mother Nature’s contribution, invest in a rain gauge. If at the end of the week she has contributed enough, hold off adding more water. If she comes up short, you will want to add some supplemental watering. If you have an irrigation system, measure how much water the sprinkler is putting down.
So, generally, you want your lawn to get about an inch of water per week. But remember certain times of the year and certain conditions can change that Rule of thumb. You must follow local regulations when there are watering bans, but just remember grass is a very resilient plant and less water is acceptable. When the rains do return, your lawn will come back with a little encouragement on your part. If you do not have an irrigation system, invest in timers and place on your faucets. This method will help you a ton.
Therefore, watering early morning gives the grass time to dry, elimination a chance for fungus. Not enough watering will stress the lawn; prolonged drought weakens the root system and invites lawn diseases like necrotic ring. You will see brown patches and mistake it for grub damage. Refer to websites on grass diseases.
If you want to help conserve water or just don’t have time to water your lawn regularly, letting your grass go dormant during the hottest months of the year can help. A dormant, or “sleeping”, lawn will turn brown, but with proper care the underground crown of the grass plant will survive. In fact, once the grass receives ample water again (either from natural precipitation or from a sprinkler), it will begin to green up and grow new leaves.
