Snake gourds through the year
Against the frost risk in Osorno
Why these dates
Sow two weeks after the last frost onto warm soil. A weight tied to the young fruit is the traditional way of getting a straight one.
Killed at 0C and needs consistently warm nights, so it is a genuinely tropical crop grown outside the tropics only in a hot summer.
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. Snake 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 Osorno.
The median frost-free season here is 266 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.
