| This lawn is starting to recover. Just the dead spots remain. Wait until mid September or even October before you begin to remove dead grass. Leave it there for mulch to prevent weeds like bermudagrass from getting started. |
If you had dead areas develop in your lawn and you are pretty convinced the damage has passed then it is time to wait until fall to repair it. Three types of problems lead to dead spots in the lawn: insects, diseases and irrigation problems. It is pretty easy to determine if the problem has passed. If it has passed, the grass surrounding the damaged area and throughout the rest of the lawn area will appear healthy and rapidly growing. All that will remain of the damage are the brown spots surrounded by healthy, vibrant, green grass.
Whatever you do, DON’T rake up the dead grass now and reseed or resod. Dead spots in a lawn are ugly. But what can be worse if you are not careful is to open up your lawn to a weed invasion, particularly bermudagrass, if you try to clean up these dead spots now. Wait. Wait until Fall, around mid September to mid October, to rake it up and reseed or resod.
If you try to reseed it now you will fail. Even laying sod right now will be difficult to keep alive. But if you rake up that dead area and expose the bare soil to sunshine and irrigation, bermudagrass WILL seed itself right into those spots. And then you WILL have a problem. Leave the dead grass alone and let it “mulch” or cover the dead area, protecting it from invasion by bermudagrass.
