High elevations	4b–5a	Use extra mulch + frost protection

👉 The goal: Plant 2–4 weeks before the ground freezes👉 Soil temperature target: 50–60°F at planting depth

🌦 What to Expect Through the Seasons

Season	Garlic Growth Stage	Tips
Fall	Roots grow underground	Add a layer of mulch
Winter	Dormant root expansion	Don’t worry if snow covers beds

🌾 Our Mulching Method for Healthy Winter Roots

At our farm, once we plant in mid-October, we cover each bed with a thick layer of organic straw mulch to:

• Reduce soil temperature swings

• Protect cloves from frost heaving

• Help with spring moisture retention

• Suppress early weeds

By March, the plants are eager to reach upward!

🧄 When Do You Harvest Garlic in Oregon?

Most Oregon garlic is harvested:

➡ Early to mid-July

Harvest indicators:

• Lower 3–4 leaves turn brown

• Upper leaves still green

• Bulbs feel firm and fully formed

Then cure garlic in a shaded, airy space for 3–4 weeks.
