Tomato in Iqaluit: soil, season and weather

In the median year the top 7 cm of soil in Iqaluit does not reach 15 °C, the minimum on the tomato card, before August; the date follows the last frost (18 June), and the bed stays cooler than the card asks. Planting out on 25 June leaves 70 days to the first autumn frost on 3 September, only 0 more than the card's 70 days to the first harvest; an unheated greenhouse, three weeks earlier, would add 21.
