GreenlyWhen to plant cucumber in A Coruña
In A Coruña, cucumber: sow seedlings around 3 April for the greenhouse and around 24 April for open ground; plant into a greenhouse around 15 May; plant out into open ground around 5 June.
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.
