Even a healthy lawn can look worse for wear after a heatwave. Brown grass is often just a lawn going dormant, but it can be something worse. Understanding how to repair patches in grass starts with knowing what you are dealing with.
Brown dormant patches of lawn are healthy underground and can burst back into life when the temperatures drop and they get some moisture. Homeowners can nurture these lawns with regular watering, light mowing, and fertilizing once the temperatures drop (this SummerGuard Lawn Food at Amazon both feeds the lawn and protects against pests). Those with dead patches, however, usually need to rake them out and sow seed to start again.
