Spring onions through the year
Against the frost risk in Srinagar
Why these dates
Sow direct every three weeks from four weeks before the last frost until about ten weeks before the first. An autumn sowing overwinters for a very early spring crop.
Tolerates about -8C. Autumn sowings survive most temperate winters and stand through cold weather without bolting.
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. Spring onions are timed for direct sowing 4 weeks before 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 55 to 75 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
