GreenlyWhen to plant cucumber in Rosario
In Rosario, cucumber: sow seedlings around 28 July for the greenhouse and around 18 August for open ground; plant into a greenhouse around 8 September; plant out into open ground around 29 September.
Last spring frost around 16 July, first autumn frost around 15 June. Frost-free days: 334 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.
