Larkspurs through the year
Against the frost risk in Srinagar
Why these dates
Sow direct four weeks before the last frost, into cool soil - the seed germinates below 15C and often refuses above 18C, which is why late sowings fail. Do not start it indoors; the taproot makes transplanting unreliable. Chilling the seed in a fridge for a fortnight before sowing improves germination markedly.
Hardy to about -12C as a seedling, so autumn sowing works well in zone 7 and milder and produces plants twice the size of spring-sown ones. Collapses in humid heat and will not persist through a subtropical summer.
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. Larkspurs are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Srinagar.
Hardiness is not the obstacle here. Srinagar is zone 7a, comfortably inside the range this crop is rated for, so an established plant should come through an average winter without protection.
The median frost-free season here is 211 days, against 90 to 110 days to first flower for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
