Zucchini in Ushuaia: soil, season and weather

In the median year the top 7 cm of soil in Ushuaia does not reach 18 °C, the minimum on the zucchini card, before August; the date follows the last frost (12 December), and the bed stays cooler than the card asks. Planting out on 19 December leaves 38 days to the first autumn frost on 26 January, only 2 more than the card's 36 days to the first harvest; an unheated greenhouse, three weeks earlier, would add 21.

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.
