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.

|---|---|---|
| Perennial ryegrasslikely yours | 8°C | 5–10 |
