Malabar spinach through the year
Against the frost risk in Yongji
Why these dates
Start indoors six weeks before the last frost and plant out two weeks after it, against a support. Growth is slow until nights stay above 20C and then becomes rampant.
Growth stops below about 10C and the plant is damaged at 2C, well before an actual frost. In cool summers it never really gets going.
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. Malabar spinach are timed from 6 weeks before that frost for an indoor start, with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Yongji.
The median frost-free season here is 234 days, against 60 to 80 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
