Bitter gourds through the year
Against the frost risk in Lianyungang
Why these dates
Sow two weeks after the last frost onto warm soil, or start indoors four weeks before it. Grow up a strong trellis so the fruit hangs straight.
Killed at 0C and unhappy below 15C. In temperate summers it needs the warmest wall you have.
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. Bitter gourds are timed from 4 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 Lianyungang.
The median frost-free season here is 248 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.
