Bottle gourds through the year
Against the frost risk in Perm
Why these dates
Sow two weeks after the last frost. Flowers open at night and are moth-pollinated, so in cool climates hand pollination in the evening improves the set considerably.
Killed at 0C. Gourds intended for drying need to stay on the vine until the stem browns, which a first frost cuts short.
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. Bottle 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 Perm.
The median frost-free season here is 135 days, against 90 to 120 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
