Gardeners urged to overseed lawns before September

August is a crucial month for lawn care, as the warmer weather begins to give way to cooler conditions. After the hot summer weather, lawns can look dry, thin, patchy, and in need of attention. With soil temperatures still warm and moisture levels starting to increase, late summer provides the ideal opportunity to help the grass recover and prepare for the months ahead.

Gardeners urged to overseed lawns before September

TL;DR

  • Late August is a prime time for overseeding lawns to improve thickness and health before autumn.
  • Key steps include removing weeds/moss, low mowing, soil aeration, topdressing, sowing seeds, and consistent watering.
  • Newly sown seeds need to be kept moist until the grass reaches 5-8cm before the first high-setting mow.
  • For poor grass growth, an autumn feed rich in potassium and phosphorus is recommended by the RHS.
