How to sow a lawn from seed

The best time of year to sow a new lawn from seed is spring or autumn, with germination taking 7 to 21 days in ideal conditions. Typical daily temperatures need to be in excess of 13ºC for successful germination.

  • Existing lawns should be removed using a turf cutter, spade or weed killer.
  • Dig over the area to a depth of 150mm-220mm, ideally using a rotovator, removing all weeds and large stones.
  • Rolawn Turf & Lawn Seeding Topsoil provides the ideal base for sowing seed. It is blended with Rolawn GroRight® Lawn Establishment Fertiliser to ensure a lawn gets off to the best possible start. Alternatively mix Rolawn Soil Improver into the soil to improve the structure and add nutrients.
  • To ensure your new lawn is fed correctly mix Rolawn GroRight® Lawn Establishment Fertiliser into the soil.
  • Firm the soil by lightly rolling or treading and rake to a level finish.
  • Sow the seed, preferably in a number of passes to achieve an even spread. Lightly rake the seed into the top 12-25mm of soil.
  • Firm down by treading or lightly rolling.
  • The seed bed must be kept moist. Water well, using a fine spray if necessary.
  • Start mowing when grass is 50-80mm high, then gradually trim down to 25mm as the lawn thickens up.
  • When seeding a new lawn, weeds need to be controlled and removed.
