When to plant bell peppers in the United States: 25 Jan – 8 Sept
Bell Pepper in the United States: plant out into open ground from 25 January to 8 September; the window opens earliest in Tampa and closes latest in Phoenix (161 cities).
Each window starts on the Greenly calendar date and ends on the last day that still leaves the crop’s days to harvest (from its card) before the average first autumn frost, plus six weeks of picking for crops harvested over weeks (tomatoes, peppers, aubergines, cucumbers, courgettes, pumpkins, watermelons, beans) — our rule; earlier in the window is safer.
