Against the frost risk in Xiamen
Why these dates
Sow from three weeks before last frost. Keep the seedbed continuously damp for the two to three weeks germination takes - this single detail decides most carrot crops.
Seedlings tolerate -6C. Mature roots can be left in the ground under mulch and lifted through winter in all but the coldest zones.
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. Carrots are timed for direct sowing 3 weeks before it, and this page simply resolves those offsets against the frost date computed for Xiamen.
