GreenlyWhen to plant tomato in Krasnoyarsk
In Krasnoyarsk, tomato: sow seedlings around 24 March for the greenhouse and around 14 April for open ground; plant into a greenhouse around 20 May; plant out into open ground around 10 June.
Last spring frost around 19 May, first autumn frost around 27 September. Frost-free days: 131 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.
