Against the frost risk in Pretoria
Why these dates
Start indoors six weeks before the last frost and plant out two weeks after it. Fruit is ready when it fills and then splits the papery husk.
Killed at 0C. It sets fruit in heat that makes tomatoes drop their flowers, which is the main reason to grow it in a hot climate.
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. Tomatillos 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 Pretoria.
The median frost-free season here is 322 days, against 75 to 100 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
