GreenlyWhen to plant cucumber in Barnaul
In Barnaul, cucumber: sow seedlings around 6 April for the greenhouse and around 27 April for open ground; plant into a greenhouse around 18 May; plant out into open ground around 8 June.
Last spring frost around 3 May, first autumn frost around 29 September. Frost-free days: 149 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.
