Lentils through the year
Against the frost risk in Huaibei
Why these dates
Sow four weeks before the last frost. Lentils are short and easily flattened by rain, so a windless site and a firm seedbed both help at harvest.
Seedlings survive to about -6C, which is why lentils are sown far earlier than most pulses.
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. Lentils are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Huaibei.
The median frost-free season here is 237 days, against 80 to 110 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
