Frequently Asked Questions
How fast does it really germinate?
Under good conditions — warm soil, adequate moisture — germination can begin in as little as 3 days. Average germination is 5–10 days depending on temperature.
How much area does the pack cover?
The 420g + 15% free pack covers approximately 14–17m² for patch repairs and overseeding. For new lawns, expect coverage of around 12m².
Can I use it in shady areas?
This is a general-purpose blend. For heavily shaded areas, a shade-specific seed mix may give better long-term results.
Do I need special equipment?
No — the seed can be sown by hand or with a basic spreader. The coated seed is easy to handle and distribute evenly.
Is it safe for pets?
Keep pets off the area until the seed has germinated and the new grass has been mown at least once. This protects both the seed and your lawn.
What if germination is slow?
Ensure the soil stays consistently moist and isn’t too cold (below 8°C slows germination significantly). Covering with a light fleece can help in cooler conditions.
Contains: Headstart® Gold, a revolutionary grass seed coating.
