When to Plant Garlic in Oregon
In Oregon, the time to plant garlic in fall runs from Sep 14 – Oct 12 in Redmond to Dec 9 – Jan 6 in Coos Bay. In Portland, it's Dec 1 – Dec 29. The average first fall frost differs by about 12 weeks across the state (Sep 14 in Redmond, Dec 9 in Coos Bay), so use the dates for the town nearest you.
Garlic is planted in fall, around the first frost, and harvested the next summer. Cloves need a cold winter to form good bulbs.
- Plant: from the first fall frost up to 4 weeks after it.
