Against the frost risk in Srinagar
Why these dates
Killed by the first frost, like basil.
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. Shiso 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 Srinagar.
The median frost-free season here is 211 days, against 70 to 90 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
