Celery through the year
Against the frost risk in Nizhniy Novgorod
Why these dates
Start ten weeks before last frost but plant out two weeks after it. Celery exposed to a fortnight below 10C after transplanting will bolt rather than form heads.
Light frost is tolerated at maturity, but cold early in life triggers bolting. This crop is unusual in that too-early planting causes failure without any visible frost damage.
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. Celery are timed from 10 weeks before that frost for an indoor start, with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Nizhniy Novgorod.
The median frost-free season here is 155 days, against 80 to 100 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
