Soil temperature at 6cm in Stirling, Scotland is currently 11.7°C, and falling about 2.0°C over the next 11 days. That depth matters because it is where grass seed sits and where roots start working, and it lags air temperature by days — which is why a warm afternoon here tells you very little on its own.

Lawns in this area are typically perennial ryegrass with fescue, which is what most lawns round here are sown with. That blend needs the soil to hold above 9°C before seed germinates reliably. Seeding conditions are open — soil is 11.7°C at 6cm and holding above 9°C.

7 of the next 10 days are good mowing days. The other 3 are held back by wet grass or soft ground. The best weekend slot right now is Saturday 8am–11am, on the basis that rain earlier today, ground firm.
