Sunflowers through the year
Against the frost risk in Gorakhpur
Why these dates
Sow a short row every two weeks until ten weeks before first frost for continuous cut flowers rather than one brief spectacle.
Seedlings are killed by frost. Once flowering, stems tolerate a light autumn frost without damage.
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. Sunflowers are timed for direct sowing 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Gorakhpur.
