When to sow Thyme in the UK

Thyme is sown to the calendar rather than to the frost, so the window is much the same wherever you garden in the UK.

Sowing and harvest dates by region

Thyme is grown to the calendar rather than to the frost, so the same dates apply across the whole UK and every region below reads the same. Where a plant’s timings do follow the frost, Plot shifts them from the Midlands and Lowland Wales baseline using Met Office average frost dates.

Growing notes

A woody evergreen sub-shrub, normally bought as a plant rather than sown each year, and best planted out from mid-spring to early summer 20-30cm apart. Winter wet, not cold, is what kills it: grow it in a pot or raised bed if your soil stays damp, and trim lightly in late spring or after flowering.
