Cucumber in Iqaluit: soil, season and weather

In the median year the top 7 cm of soil in Iqaluit does not reach 18 °C, the minimum on the cucumber card, before August; the date follows the last frost (18 June), and the bed stays cooler than the card asks. 70 days separate planting out (25 June) from the first autumn frost (3 September); the card's 34 days to the first harvest leave 36 for picking, so a start 5 weeks late would still fit.
