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.

Preparing the ground

  • Remove existing lawns or weeds: Clear any existing grass using a turf cutter, spade, or approved weed killer.

  • Cultivate the soil: Dig over the area to a depth of 150mm-220mm, ideally using a rotovator, removing all weeds and large stones.

  • Add nutrient-rich topsoil: 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.

  • Firm and level the soil: Lightly roll or tread the soil to firm it down, then rake to a smooth, level finish.

Sowing the seed

  • Choose the right seed: For premium results, use Medallion® Lawn Seed 1kg for smaller areas or Medallion® Lawn Seed 20kg for larger lawns. Both contain the same professional-grade seed mix used in Rolawn’s award-winning Medallion® Turf.

  • Apply evenly: Sow the seed in multiple directions to ensure even coverage, lightly raking it into the top 12–25mm of soil.

  • Firm: Firm down by treading or lightly rolling.

  • Water: The seed bed must be kept moist. Water well, using a fine spray if necessary.

Aftercare

  • Keep the seeded area consistently moist until established, watering daily during dry spells.

  • 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 early to prevent competition with young grass.

Important update: Temporary 6.5% surcharge effective 7 April 

At Rolawn, we are committed to maintaining the high standards of quality and service our customers expect, so we want to be open with our customers about a change that will affect pricing from Tuesday 7th April. 

This decision has been taken in response to disruption to energy supplies, which has led to significant increases in wholesale prices, affecting not only fuel and fertiliser but also costs throughout our wider supply chain. As a business that relies heavily on fuel for both transport and operations, these sustained cost pressures have become increasingly difficult to absorb.  

While we have worked hard to mitigate the impact, the scale and pace of recent price increases have now exceeded what we can sustain internally, and we therefore need to recover a proportion of these externally driven increases. 

From Tuesday 7th April, a temporary 6.5% surcharge will apply to all products.  

We know that any increase in price is frustrating, particularly at a time when many businesses and households are already feeling under pressure. That is why we want to be clear that this is not a decision we have made lightly, and not one we wanted to make. It has been introduced solely to help offset unavoidable cost inflation and allow us to continue delivering the quality, reliability and service standards associated with Rolawn. 

We will continue to monitor market conditions closely and will review this surcharge as soon as circumstances allow, providing reasonable notice of any changes. We recognise that any price increase is unwelcome, but this step is necessary to ensure the continuity and reliability of our operations during a period of ongoing uncertainty. 

We remain committed to providing the quality, reliability and service standards you expect from Rolawn, and we truly appreciate your understanding and continued support. 

If you have any questions, please contact our customer support team who will be happy to help.
