Against the frost risk in Huayin
Why these dates
Sow as soon as soil is workable - six weeks before last frost is normal. In mild-winter climates an autumn sowing overwinters and crops six weeks earlier than any spring sowing can.
Established pea plants shrug off -6C. Seedlings tolerate frost easily; it is heat, not cold, that ends the crop.
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. Peas are timed for direct sowing 6 weeks before it, and this page simply resolves those offsets against the frost date computed for Huayin.
The median frost-free season here is 214 days, against 55 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
