Against the frost risk in Dali
Why these dates
Start indoors 10 weeks before the last frost and plant out after it, keeping the crown at soil level rather than buried. Remove the lower leaves in late summer so the root swells cleanly.
Stands to about -8C in the ground and improves with a touch of frost, so it can be left and lifted as needed well into winter.
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. Celeriac 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 Dali.
The median frost-free season here is 311 days, against 110 to 140 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
