When to sow Radish in the UK
Radish 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
Radish 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.

| South West Coast and Cornwall | late February to late August | late March to early October |
