GreenlyWhen to plant cucumber in Dallas
In Dallas, cucumber: sow seedlings around 23 January for the greenhouse and around 13 February for open ground; plant into a greenhouse around 6 March; plant out into open ground around 27 March.
Last spring frost around 19 February, first autumn frost around 5 December. Frost-free days: 289 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.
