How to Use

For New Lawns:

• Clear the area of weeds, stones and debris.
• Rake the soil so it’s loose and crumbly.
• Shake the seed evenly across the prepared ground.
• Rake again lightly so the seed sits just under the surface.
• Water well and keep the soil moist while the grass establishes.
• Mow when the grass reaches 8cm.

For Overseeding:

• Cut your existing lawn short and remove clippings and moss.
• Shake the seed evenly over thin or patchy areas.
• Water well to start germination.
• Recommended overseeding rate: 1kg covers 60m².

Top Tips for Best Results

• Sow when the soil is warm and the risk of frost has passed (above 5°C).
• Ideal sowing times: late spring, or late summer into autumn.
• Use a lawn fertiliser once the grass has started growing.
• Protect from birds with netting if needed.
• For best results, store grass seed in a cool, dry place until use.
