Against the frost risk in Goyang-si
Why these dates
Germination takes three to four weeks. Sow indoors eight weeks before last frost or direct once soil warms; either way, patience is required.
Survives -10C and often overwinters to produce an early spring crop before running to seed in its second year.
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. Parsley are timed from 8 weeks before that frost for an indoor start, with planting out 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Goyang-si.
The median frost-free season here is 223 days, against 70 to 90 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
