GreenlyWhen to plant peas in Cologne
In Cologne, peas: sow straight into the bed around 16 March.
Last spring frost around 6 April, first autumn frost around 20 November. Frost-free days: 228 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.
