GreenlyWhen to plant tomato in Valladolid
In Valladolid, tomato: sow seedlings around 10 February for the greenhouse and around 3 March for open ground; plant into a greenhouse around 8 April; plant out into open ground around 29 April.
Last spring frost around 6 April, first autumn frost around 27 November. Frost-free days: 235 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.
