GreenlyWhen to plant zucchini in Ternopil
In Ternopil, zucchini: sow seedlings around 28 March for the greenhouse and around 18 April for open ground; plant into a greenhouse around 29 April; plant out into open ground around 20 May.
Last spring frost around 21 April, first autumn frost around 20 October. Frost-free days: 182 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.
