Calibrated to Stirling

Two dates set the growing year in Stirling.

Every sowing, planting-out and harvest window on this site is worked out from the average last spring frost and first autumn frost in Stirling, taken from 30 years of Met Office records, and what each plant can put up with.

They're averages, not promises. A late frost can still flatten your courgettes, so keep an eye on the forecast. That's gardening.
