Broad beans sowing calendar (UK)

Sow under coverFeb-Mar (in pots)
Sow / plant outdoorsAutumn Oct-Nov or spring Feb-Apr
HarvestJun-Aug (autumn-sown from May)

Hardy enough to overwinter: autumn-sow a tough cultivar like 'Aquadulce Claudia' (Oct-Nov) for an early May-Jun crop, or sow in pots under cover from February for planting out in spring. On cold, wet or windy sites spring sowing is more reliable.

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 broad beans.
