Seed Sowing FAQ

Expert UK Advice for March 2026
LIVE INTEL
When is the best time to sow grass seed in March? +
March is the ideal preparation month. For the best results, wait for our 'Tractor' light to turn Green, which indicates soil temperatures have consistently reached the 8-10°C required for germination.
Can I sow grass seed if a frost is forecast? +
While a light frost won't usually kill the seed, it will keep it dormant. If your region is showing 'Red' or 'Amber' due to cold nights, it's better to wait for a warmer window to ensure the seed doesn't rot in cold, wet soil.
How long does grass seed take to grow in early Spring? +
In March and April, germination typically takes 14 to 21 days. As the days get longer and the soil warms up, this can speed up to 7-10 days. Always check your regional 'Live Intel' status above for current growth speeds.
Do I need to clear moss before sowing new seed? +
Yes. March is the peak time for moss removal. Scarify your lawn to remove thatch and moss first, then use our tracker to find a 'Green' window to over-seed the bare patches.
Should I water my new grass seed in March? +
Spring weather can be deceptive. If you have 2-3 dry, sunny days in a row, give your new seed a light misting in the evening. You want the soil to stay moist but never puddled or soaking wet.
