Chives through the year
Against the frost risk in Dongguan
Why these dates
Sow once and divide every third year. First-year plants are thin; the crop is properly established in year two.
Fully dormant-hardy to -25C. Emerges as soon as soil temperature passes about 5C, often weeks before the last frost.
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. Chives are timed from 8 weeks before that frost for an indoor start, with planting out 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Dongguan.
