Against the frost risk in Skardu
Why these dates
Start indoors six weeks before the last frost, which is unusually early for a cucurbit, and plant out once nights hold above 15C. Sponges need around 150 frost-free days.
Killed at 0C. Fruit left to mature for sponges must dry on the vine, so a late frost ends the crop before the fibre has set.
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. Luffa are timed from 6 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 Skardu.
The median frost-free season here is 95 days, against 120 to 180 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
