Sweet peppers through the year
Against the frost risk in The Bronx
Why these dates
Peppers germinate slowly and unevenly below 24C, so start them two weeks ahead of tomatoes. Bottom heat makes a bigger difference here than for any other common vegetable.
Frost kills peppers outright, but the more common failure is chilling injury: a week of nights near 5C stunts a young plant for the rest of the season without visibly damaging it.
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. Sweet peppers 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 The Bronx.
The median frost-free season here is 203 days, against 60 to 90 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
