Oregano sowing calendar (UK)
| Sow under cover | Mar-May |
|---|---|
| Sow / plant outdoors | Plant out late May-Jun |
| Harvest | Jun-Oct |
A hardy perennial usually raised under cover at 18-20C, then hardened off and planted out after the last frost (late May-early June). Flavour is best just before the flowers open in mid-summer.
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 oregano.
