When to plant tomatoes in Poland: 9 May – 30 July
Tomato in Poland: plant out into open ground from 9 May to 30 July; the window opens earliest in Zielona Góra and closes latest in Gdańsk (20 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.
