Against the frost risk in Rohtak
Why these dates
Sow direct in succession from four weeks before the last frost, then stop for high summer and resume in late summer. An autumn sowing under cover picks through winter.
Tolerates about -8C and grows through mild winters in a cold frame, which is when it is at its best.
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. Chervil are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Rohtak.
