When to plant peas in the United Kingdom: 18 Jan – 18 Sept

Peas in the United Kingdom: sow straight into the bed from 18 January to 18 September; the window opens earliest in Brighton 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.
