When to plant garlic in Belgium: 16 October – end of December

Garlic in Belgium: plant from 16 October to the end of December; the window opens earliest in Charleroi and closes latest in Brussels (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).
