GreenlyWhen to plant cucumber in Houston
In Houston, cucumber: sow seedlings around 23 December for the greenhouse and around 13 January for open ground; plant into a greenhouse around 3 February; plant out into open ground around 24 February.
Last spring frost around 17 February, first autumn frost around 27 November. Frost-free days: 283 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.
