GreenlyWhen to plant pumpkin in Winnipeg
In Winnipeg, pumpkin: sow seedlings around 27 March for the greenhouse and around 17 April for open ground; plant into a greenhouse around 3 May; plant out into open ground around 24 May.
Last spring frost around 12 May, first autumn frost around 12 October. Frost-free days: 153 days.
The dates follow the Greenly calendar: open ground a week after the last frost once the soil is warm enough for the crop, frost-hardy crops three weeks before it, an unheated greenhouse three weeks earlier, seedlings sown so they are ready on the day. In a cold year allow a week or two more.
