Chilli peppers through the year
Against the frost risk in Pretoria
Why these dates
Hotter species such as habanero need 10 to 12 weeks indoors, not nine. If your frost-free season is under 120 days, treat a chilli as a container plant you can move.
Identical frost sensitivity to sweet peppers. Because the fruit ripens late, the first autumn frost usually decides your final yield more than the last spring one does.
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. Chilli peppers are timed from 9 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 70 to 100 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
