Sweet peas through the year
Against the frost risk in Konya
Why these dates
Sow in autumn and overwinter in a cold frame in zone 6 and warmer, or start ten weeks before last frost. Pinch at four true leaves.
Young plants take -8C and benefit from the cold. This is a flower where autumn sowing genuinely doubles the season.
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. Sweet peas are timed from 10 weeks before that frost for an indoor start, with planting out 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Konya.
The median frost-free season here is 194 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.
