GreenlyWhen to plant tulip in Barcelona
In Barcelona, tulip: plant around 12 November, a month before the first autumn frost.
Last spring frost around 24 January, first autumn frost around 12 December. Frost-free days: 322 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.
