Sweetcorn through the year
Against the frost risk in Tarsus
Why these dates
Seed rots in cold wet soil. Sowing a week after last frost into 15C soil beats sowing on the frost date into 10C soil almost every time.
Seedlings survive a very light frost if the growing point is still below soil level, but growth stalls. Mature plants are killed outright.
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. Sweetcorn are timed for direct sowing 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Tarsus.
The median frost-free season here is 309 days, against 60 to 100 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
