Frost risk Start indoors Plant out Harvest Today

Why these dates

Start indoors six weeks before the last frost and plant out around it, aiming for the head to form in the cooling weather of early autumn rather than in midsummer heat.

Hardy to about -5C. The curd itself is more tender than the leaves and browns after a hard frost, so cut once it is sized rather than leaving it out.

Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Romanesco are timed from 6 weeks before that frost for an indoor start, with planting out 1 weeks before it, and this page simply resolves those offsets against the frost date computed for Delhi.
