Ginger through the year
Against the frost risk in Pyongyang
Why these dates
Sprout the rhizome indoors eight weeks before the last frost and move outside two weeks after it. Young stem ginger can be lifted at six months; mature ginger needs the full season.
Killed at 0C and dormant below 15C. Harvest when the leaves yellow, which in a temperate climate means before the first frost rather than at true maturity.
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. Ginger are timed from 8 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 Pyongyang.
The median frost-free season here is 204 days, against 240 to 300 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
