Pumpkin in Coyhaique: soil, season and weather

In the median year the top 7 cm of soil in Coyhaique does not reach 18 °C, the minimum on the pumpkin card, before August; the date follows the last frost (3 December), and the bed stays cooler than the card asks. Only 35 days lie between planting out (10 December) and the first autumn frost (14 January), against the card's 75 days to the first harvest: even an unheated greenhouse, three weeks earlier, falls 19 days short without heat or a faster variety.
