Yardlong beans through the year
Against the frost risk in Delhi
Why these dates
Sow two weeks after the last frost onto warm soil, up a tall support. Pick at about 40cm, before the seeds swell, and pick every second day.
Killed at 0C. Growth stalls below 18C, so in cool summers the plant climbs without ever flowering usefully.
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. Yardlong beans are timed from 3 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 Delhi.
