Dill sowing calendar (UK)
| Sow under cover | n/a |
|---|---|
| Sow / plant outdoors | Apr-Jul |
| Harvest | Jun-Oct |
Direct sow outdoors from mid-spring - dill has a taproot and resents being moved, so avoid module-raising and transplanting. Succession sow every 3-4 weeks for continuous leaf; collect ripe seed in late summer/autumn.
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 dill.
