New Zealand spinach through the year
Against the frost risk in Mexico City
Why these dates
Soak the hard seed overnight and sow a week after the last frost. Pick the growing tips continuously and the plant spreads sideways instead of setting seed.
Killed at 0C. It often self-seeds and returns the following year from seed that has overwintered in the soil, which can look like the plant surviving.
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. New Zealand spinach are timed from 4 weeks before that frost for an indoor start, with planting out 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Mexico City.
The median frost-free season here is 281 days, against 55 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
