Soil temperature

11.8°C53°F

at 6cm — germination depth

Cooling over the next 11 days.

Seeding conditions are open — soil is 11.8°C at 6cm and holding above 9°C.

Almost every UK and Irish lawn is a ryegrass and fescue mix, whether it was sown or turfed. We assume that, and use9°C as the seeding threshold.

I know what grass I have

The differences are small. Ryegrass is the quickest off the mark; bluegrass is the slowest and wants the warmest soil. Everything else sits between.

Soil temperature at 6cm for reliable germination. Sources onthe method page.
