When to sow Parsnip in the UK

Parsnip 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

Parsnip 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

Sow direct from March to early May once the soil is around 12C, using fresh seed every year, and never start it indoors as the tap root will not transplant. Roots are very hardy and can stay in the ground until needed, but a windowbox is far too shallow - it needs a pot at least 40cm deep.
