Why these dates

Plant dry bulbs in early autumn, as soon as they are available and while they still feel firm - they dry out faster than any other common bulb, and a shrivelled one will not grow. Far better, move them in the green: lift and split clumps just after flowering, while the leaves are still up.

Hardy to -30C and flowers straight through frost and snow. Wants a cold winter and cool summer shade; it is the least happy of the common bulbs in a hot climate and rarely persists past zone 7.

Snowdrops are anchored to the first autumn frost rather than the last spring one, so the planting window on this page counts backwards from the end of the season in Zhaoqing instead of forwards from its start.

Zhaoqing sits in zone 10a, which is milder than this crop wants, and a winter that never really arrives is its own problem. The dates below still describe the right time of year; the open question is survival rather than timing.

The median frost-free season here is 332 days, against 110 to 160 days to first flower for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
