Sowing & Establishment

How to sow a new lawn with lawn repair seed

1 - Clear the area
Clear the area and remove any stones, weeds and other debris.

2 - Improve the soil
Cultivate the area to a depth of 15cm and remove any debris that is unearthed. For heavy clay soils, optionally, mix in sharp sand.

3 - Create a level seed bed
Level and rake over the area. Use a lawn roller to firm the soil, if required.

4 - Allow the soil to settle
If possible, leave the soil for a week to allow a flush of weeds to come through; remove before sowing.

5 - Final ground preparation
Rake the area to loosen the top layer of soil. Apply our Pre-Seeding Lawn Fertiliser and rake into the soil.

6 - Sowing the grass seed
Spread the grass seed evenly across the area at 50g/sqm. A spreader can be used for accurate application.

7 - Rake and roll
This step is essential for successful establishment. Gently rake over the area again to incorporate the seed into the top 1-2cm of the soil, so that there is very little seed still visible on the surface. Then lightly roll or tread the seeds in to ensure good seed-to-soil contact. A harrow can be used for large areas.

8 - Water
If going through a period of drought, water the area every other evening for the first few weeks. If regular rainfall, manually watering will not be necessary.

9 - Mowing the lawn
Under optimum conditions, the seed should germinate within approximately 10-14 days. Once it reaches 3-4 inches, cut the lawn for the first time, gradually lowering the height with each subsequent cut as desired.

 

How to repair an existing lawn with lawn repair seed

1 - Prepare the grass
Cut the existing grass short and almost scalp the lawn with the lawn mower. Remove any dead grass, debris and thatch.

2 - Improve the soil
Scarify or rake the surface to loosen the top layer.

3 - Aerate the lawn
Optionally, to aid drainage, use a garden fork or aerator to create small holes of around 1-2 inches deep.

4 - Sow the grass seed
Spread the grass seed evenly across the area at a minimum of 25g/sqm. A spreader can be used for accurate application.

5 - Rake and roll
This step is essential for successful establishment. Gently rake over the area again to incorporate the seed into the top 1-2cm of the soil, so that there is very little seed still visible on the surface. Then lightly roll or tread the seeds in to ensure good seed-to-soil contact. A harrow can be used for large areas.

6 - Water
If going through a period of drought, water the area every other evening for the first couple of weeks. If regular rainfall, manual watering won’t be needed.

7 - Mowing the lawn
Under optimum conditions, the seed should germinate within approximately 10-14 days. Once it reaches a height of 3-4 inches, cut the lawn for the first time, gradually lowering the height with each subsequent cut as desired.

Mowing New Grass
  • Wait until new grass reaches around 7-10cm tall before the first cut
  • Use the mower on its highest setting for the first few cuts
  • Never remove more than one-third of the grass height in a single mow
  • Ensure the ground is reasonably firm and dry before mowing
  • Regular light mowing helps encourage a thicker, denser lawn
Maintenance

How to maintain your lawn after you’ve used lawn repair seed

 

1 - Germination

The best time to sow our Renovator Lawn Seed is from March-October, when the soil temperature is around 8-10 degrees. Under optimum conditions, the seed should germinate within 10-14 days from sowing.

2 - Watering

Grass seed requires warmth, moisture and light to germinate. Typically, autumn will provide more favourable conditions for sowing in terms of moisture, however, if there is a period of drought, manually watering the seeds will be beneficial – this can be done every other evening to allow the moisture to soak into the soil.  

3 - Mowing

Allow your lawn to grow to around 3-4 inches in height before cutting your lawn. This can be reduced by half an inch each time until you reach the desired height. An established lawn sown with our Renovator Lawn Grass Seed can be cut as low as 20-40mm. It is important to remove the grass cuttings as dead grass will prevent sunlight from getting to the new grass.

4 - Fertilisation

Regularly fertilising your lawn will provide it with the nutrients it requires to stay lush and green all year-round.

Once the lawn is four months old, you can apply our quick release fertilisers. Dependent on the time of year, choose our Spring and Summer Fertiliser or Autumn and Winter Fertiliser. Around four applications a year, with a minimum of three months between applications will provide sufficient nutrients for an established lawn. 

5 - Scarifying, Aerating and Overseeding

Both autumn and spring are good times of year to aerate and scarify your lawn, and tackle any worn areas by overseeding. Aerating your lawn is optional, but particularly useful if you have heavier clay soils where waterlogging may be a problem. Use an aerator or a garden fork to aid drainage. Scarifying is also beneficial in removing any dead grass, moss and thatch that may be hindering the growth of your existing grass.

After this process, there may be some bare patches amongst your lawn – this is the perfect time to overseed when the soil temperature is optimum and moisture is plentiful. We recommend overseeding with the same grass seed mixture as you have previously sown for a uniform appearance.

6 - Controlling Weeds

Unfortunately, as comes with seedbed preparation, weed seeds can lay dormant in the soil and it’s not until they are disturbed and the conditions are ideal, that they then can start to germinate.

If you find that weeds appear during establishment, these will generally be taken out by regular mowing once the lawn has reached around 3-4 inches in height. If the weeds are recurring, after 4 months, a Selective Weedkiller can be applied which will kill common lawn weeds, whilst leaving the existing grass unharmed.

7 – Controlling Moss

Moss can become problematic in areas that are particularly damp and shady. Moss Killer is best applied during March-October when moss is actively growing.

On a newly established area (under 5 months old), avoid using a moss killer as this will be too strong for the lawn. Instead, rake over the area to loosen and remove the moss and add further seed if required.

Once the lawn is established (over 5 months old), a moss killer can be applied such as our Lawn, Feed and Weed plus Moss Killer for light areas of moss, or our Lawn Revivor and Moss Destroyer for more heavily infested areas. After using these, the moss will turn black within a couple of weeks, rake and remove this and overseed with one of our lawn seeds.

FAQs

How do I repair a lawn by overseeding with new grass seed?

Repairing a lawn usually involves overseeding damaged areas with fast-germinating grass seed. 

To repair a patchy lawn, we recommend: 

  • Loosening the soil and creating small holes with a garden fork.
  • Applying lawn repair grass seed and keeping the area moist while it germinates.
  • As a general rule, when overseeding an existing lawn you should apply approximately half of the recommended full seeding rate. 

Lawn renovations using amenity perennial ryegrass seed help fill bare patches, thicken thin grass and restore lawn durability quickly, with germination often occurring in 7–10 days with ideal weather and care conditions.

Overseeding is intended to fill in thin or bare areas rather than establish a completely new lawn, so a lighter application helps improve lawn density without overcrowding the existing grass.

What is the best grass seed for repairing a damaged lawn?

The best grass seed for repairing a lawn is a fast-germinating, hard-wearing variety such as amenity perennial ryegrass. It establishes quickly, fills bare patches and helps restore lawn density after wear, drought, pets, or heavy use.

BS Renovator Lawn Repair Grass Seed uses high-quality, dwarf amenity perennial ryegrass varieties specifically selected for rapid lawn repair and the renovation of lawns and sports pitches, to create a thick, durable and resilient sward.

What is lawn overseeding and why is it important?

Overseeding a lawn is the process of spreading grass seed over an existing lawn to improve density, repair damage and rejuvenate tired grass. It is one of the most effective lawn renovation techniques because it thickens turf, fills thin areas and introduces stronger grass varieties without removing the existing lawn.

How do you repair a patchy lawn with grass seed?

To repair a patchy lawn, follow these simple steps:

  1. Rake the area to remove dead grass, debris and weeds
  2. Loosen the soil to relieve compaction
  3. Create small holes with a garden fork across the damaged area to improve aeration and help grass seed establish
  4. Apply the lawn repair grass seed evenly over the prepared soil
  5. As a general rule, when overseeding an existing lawn you should apply approximately half of the recommended full seeding rate.
  6. Lightly rake the seed into the surface to ensure good seed-to-soil contact
  7. Firm the area by gently rolling or treading the ground
  8. Water regularly to keep the soil moist while the grass germinates

If you're looking for more information on how to repair your lawn with grass seed, we've got a blog that shares everything you need to know. Read our blog sharing our advice on how to repair your lawn with grass seed.

When is the best time to overseed a lawn?

The best time for overseeding lawn areas is typically:

  • Spring (March–May) when soil temperatures rise
  • Early autumn (September–October) when soil is warm and moisture levels improve

These periods provide the ideal growing conditions for fast lawn establishment and successful lawn renovations.

 

Can overseeding fix a thin or struggling lawn?

Yes. Overseeding is one of the most effective ways to repair a thin lawn. By introducing new grass into the existing turf, overseeding improves lawn density, strengthens grass coverage and helps lawns recover from wear, drought damage, pets or heavy foot traffic. Make sure you follow the basic steps of how to overseed a lawn first.

Can lawn repair grass seed fill bare patches?

Yes. Lawn repair grass seed is specifically designed to fill bare patches and worn areas. When applied correctly with proper soil contact and moisture, the seed will germinate and establish new grass plants that blend into the existing lawn.

How much grass seed do you need for lawn repair or overseeding?

When overseeding an established lawn, it is generally recommended to apply around 50% of the standard seeding rate.

This lower rate allows new grass seed to fill in thin or patchy areas while preventing excessive competition between new and existing grass plants.

Applying too much seed can lead to overcrowding and weaker growth.

 

Can I just scatter grass seed on top of an existing lawn?

Technically, yes, you can just scatter grass seed on top of a lawn. However, it will reduce the chances of it germinating and growing as effectively as it would with the recommended preparation and sowing technique.

How long until I can use grass after repairing it?

We recommend avoiding any areas you have repaired for 8-12. This is to allow it to germinate and establish itself without being damaged by use. Some grass might take slightly longer, so staying off your fresh grass for as long as possible is best.
