Garlic through the year
Against the frost risk in Suining
Why these dates
Plant four to six weeks before your first autumn frost so roots establish before the ground cools. Hardneck types require a genuine cold period and will not bulb properly in mild-winter climates.
Survives -20C under mulch. Hardnecks need six to eight weeks below 10C to form cloves, making this a crop that actively requires winter.
Garlic are anchored to the first autumn frost rather than the last spring one, so the planting window on this page counts backwards from the end of the season in Suining instead of forwards from its start.
The median frost-free season here is 311 days, against 240 to 270 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
