GreenlyWhen to plant eggplant in Christchurch
In Christchurch, eggplant: sow seedlings around 1 September for the greenhouse and around 22 September for open ground; plant into a greenhouse around 10 November; plant out into open ground around 1 December.
Last spring frost around 10 August, first autumn frost around 5 June. Frost-free days: 299 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.
