GreenlyWhen to plant tulips in New Zealand: 20 April – end of June
Tulip in New Zealand: plant from 20 April to the end of June; the window opens earliest in Queenstown and closes latest in Dunedin (2 cities).
From a month before the first autumn frost, so the roots grow before winter, to the late-planting limit on each crop’s page (about two weeks before the ground freezes, by ten years of weather).
