How to Use

For New Lawns:

1. Clear the area of weeds, stones and debris

2. Rake the soil so it’s loose and crumbly

3. Shake the seed evenly across the prepared ground

4. Rake lightly so the seed is just covered

5. Water well and keep the soil moist while establishing

6. Mow when the grass reaches around 8cm

For Overseeding:

1. Mow the lawn short and remove clippings

2. Rake the surface to loosen the soil

3. Apply seed evenly across thin or patchy areas

4. Lightly rake to help seed contact the soil

5. Water regularly until established
