When to plant garlic in Italy: 11 August – end of December
Garlic in Italy: plant from 11 August to the end of December; the window opens earliest in Aosta and closes latest in Rome (41 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).
