Cape gooseberries through the year
Against the frost risk in Mexico City
Why these dates
Start indoors 8 weeks before the last frost and plant out after it, exactly as for tomatoes. In a frost-free climate it persists for several years and fruits far more heavily in its second.
Killed by the first real frost where it is grown as an annual, which is what ends the season rather than any decision of the gardener's.
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. Cape gooseberries are timed from 8 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 Mexico City.
Hardiness is not the obstacle here. Mexico City is zone 9b, comfortably inside the range this crop is rated for, so an established plant should come through an average winter without protection.
The median frost-free season here is 281 days, against 100 to 130 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
