GreenlyWhen to plant zucchini in Khabarovsk
In Khabarovsk, zucchini: sow seedlings around 6 April for the greenhouse and around 27 April for open ground; plant into a greenhouse around 8 May; plant out into open ground around 29 May.
Last spring frost around 30 April, first autumn frost around 16 October. Frost-free days: 169 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.
