Repairing flooding on your lawn

With all this rain we’ve been getting this wet October so far, there’s going to be a few flooded lawns around the country.

Here are a few tips we’ve put together for you if your lawn floods:

Lawn flooded for less than 4 days

Lawns that have been under floodwater and associated silt for less than four days will recover quickly. Once the silt has dried the following treatment plan will need to be considered.

  • Remove all debris that may have been left on the lawn by the flooding
  • The lawn surface will need to be raked to break up the silt crust
  • Aeration will be necessary for helping to dry the lawn profile
  • After aeration, the lawn will benefit from a light top dressing which should be raked into the lawn surface
  • Application of fertiliser will encourage the recovery of the grasses
  • Overseeding is likely but should be completed in the spring to allow for good germination.

Lawn flooded for more than 4 days

Lawns that have been under floodwater for more than four days are likely to require major renovations, especially as they may be covered in a thicker layer of silt which will result in much if not all of the grass is dead.

  • Remove all debris from the lawn
  • Remove as much of the silt layer as possible
  • All grass vegetation will need to be removed through scarification or by the use of a turf cutter
  • Where the lawn levels have been disturbed there will be the need for topsoil to be applied
  • Cultivate the lawn surface, mixing the topsoil with the lawn profile, diluting all remaining silts
  • Prepare a level surface through raking in various directions
  • If you wish the lawn to be returned to perfect condition before the winter then turf will be the only option at this time of the year
  • If the preferred option is for overseeding, this will need to wait until the spring to allow for good germination.
