GreenlyWhen to plant bell pepper in Helsinki
In Helsinki, bell pepper: sow seedlings around 14 March for the greenhouse and around 4 April for open ground; plant into a greenhouse around 27 May; plant out into open ground around 17 June.
Last spring frost around 6 May, first autumn frost around 20 October. Frost-free days: 167 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.
