Pumpkin in Juneau: soil, season and weather

In the median year the top 7 cm of soil in Juneau does not reach 18 °C, the minimum on the pumpkin card, before August; the date follows the last frost (27 May), and the bed stays cooler than the card asks. 125 days separate planting out (3 June) from the first autumn frost (6 October); the card's 75 days to the first harvest leave 50 for picking, so a start 7 weeks late would still fit.

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.
