How to Use

Creating a New Lawn or Repairing Bare Patches

1. Clear away stones, debris and unwanted weeds.

2. In dry conditions, thoroughly water the ground the day before sowing.

3. Dig the soil to approximately 20–25cm deep, breaking down large lumps as you work.

4. Firm the soil by treading it down, then rake to produce a flat, even seed bed.

5. Mix the seed thoroughly before application.

6. Sow evenly at 30g per m².

7. Lightly rake the seed into the soil surface.

8. Firm the area gently to ensure good seed-to-soil contact.

9. Water carefully with a fine-rose watering can or sprinkler, avoiding displacement of the seed.

Overseeding an Existing Lawn

Mow the existing lawn closely, then rake or scarify to remove dead material and open the soil surface.

Fill and level shallow hollows where necessary.

Apply the seed evenly at 25g per m², lightly rake it into the surface and firm gently.

Water thoroughly after sowing and continue watering during dry weather while the young grass establishes.

Sowing Rates & Coverage

The 144m² overseeding figure is calculated from the verified 3.6kg pack weight and the published overseeding rate of 25g/m².

Sowing & Establishment

For reliable establishment, sow when soil temperature remains consistently around 10–18°C.

Spring and autumn generally provide the most favourable combination of soil temperature and natural moisture. Avoid sowing during frost, drought or other extreme conditions.

Good seed-to-soil contact and consistent moisture are essential. Do not allow the prepared seed bed to dry out during germination and early establishment.

Aftercare

Keep newly seeded areas moist, watering with a fine spray when rainfall is insufficient.

Minimise foot traffic until the young grass has established properly.

Once the grass is ready for its first cut, use sharp mower blades and remove only a modest amount of leaf. Gradually reduce the cutting height over subsequent mowing rather than immediately cutting the young lawn very short.

Regular mowing and appropriate feeding once established will help maintain a thick, healthy lawn.

Good to Know

Gro-Sure Multi-Purpose Lawn Seed is designed to balance appearance with everyday durability, making it a practical choice where a versatile lawn is preferred over a specialist fine ornamental mixture.

The seed is coated for improved germination and quicker seedling establishment and treated to help deter birds.

At the published new-lawn rate of 30g/m², the full 3.6kg bag covers exactly 120m².

If the lawn has recently been treated with a weedkiller or combined lawn treatment, always observe the treatment manufacturer's specified interval before sowing new grass seed.

Storage

Store in a cool, dry place, protecting the seed from moisture.

Keep unused seed securely sealed between applications. Mix the contents before sowing because different seed varieties can settle during transport and storage.

Wash hands after handling treated grass seed and follow all instructions provided on the packaging.
