Nasturtiums through the year
Against the frost risk in Shenzhen
Why these dates
Direct sow after last frost. The large seed germinates readily and transplanting is unnecessary.
Frost-tender throughout. Often the first plant in the garden to signal that a frost occurred overnight.
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. Nasturtiums are timed for direct sowing 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Shenzhen.
