Coriander sowing calendar (UK)
| Sow under cover | n/a |
|---|---|
| Sow / plant outdoors | Mar-Sep |
| Harvest | May-Nov |
Best direct sown where it is to grow, as it dislikes root disturbance and bolts if transplanted or stressed. Sow little-and-often; spring and late-summer/early-autumn sowings give the best leaf as midsummer heat triggers bolting.
UK timing runs on the last-frost date, not a USDA zone. Most of Britain sees its last frost around mid-May, with the north and exposed inland gardens a week or two later and the mild south-west and coast earlier. Tender crops start under cover and only go out once frost has passed; hardy crops can be direct-sown as soon as the soil is workable.
Timing aligned with the RHS grow-your-own guide for coriander.
