Against the frost risk in Jining
Why these dates
Only three weeks indoors: cucumbers hate root disturbance, so sow into modules or pots you can plant whole. A second sowing three weeks after the first extends picking by a month.
Cold soil rots cucumber seed before it germinates. If soil is below 18C, wait - the seed is cheaper than the fortnight you would lose.
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. Cucumbers are timed from 3 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 Jining.
The median frost-free season here is 227 days, against 50 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
