When to plant garlic in South Korea: 1 October – end of December

Garlic in South Korea: plant from 1 October to the end of December; the window opens earliest in Chuncheon and closes latest in Busan (10 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).
