GreenlyWhen to plant tomatoes in Argentina: 24 July – 9 March
Tomato in Argentina: plant out into open ground from 24 July to 9 March; the window opens earliest in San Fernando del Valle de Catamarca and closes latest in Salta (18 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.
