Pumpkin in Aosta: soil, season and weather

In Aosta the soil, not frost, sets the date: the last frost is over around 6 June, but the top 7 cm of soil reaches 18 °C — the minimum on the pumpkin card — only around 1 July, 25 days later. Between planting out (1 July) and the first autumn frost (10 September) there are 71 days, 4 fewer than the card's 75 to the first harvest; in an unheated greenhouse, three weeks earlier, 17 would be left to spare.
