GreenlyWhen to plant pumpkin in Rostov-on-Don
In Rostov-on-Don, pumpkin: sow seedlings around 8 March for the greenhouse and around 29 March for open ground; plant into a greenhouse around 14 April; plant out into open ground around 5 May.
Last spring frost around 29 March, first autumn frost around 9 November. Frost-free days: 225 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.
