Against the frost risk in Donghai
Why these dates
Sow fresh seed four weeks before the last frost, thickly, because germination is poor even at its best. Cut the whole plant at about 20cm before it toughens.
Tolerates around -3C. The season ends in early summer when the plant turns woody rather than because of any cold.
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. Agretti are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Donghai.
The median frost-free season here is 329 days, against 50 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
