When to plant bell peppers in the United Kingdom: 12 Jun – 11 Aug
Bell Pepper in the United Kingdom: plant out into open ground from 12 June to 11 August; the window opens earliest in London and closes latest in Swansea (40 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.
