Can I Grow Garlic in Containers in Zones 3–5?
Yes! Garlic can be grown successfully in containers in cold zones like 3–5, as long as you mimic the conditions it needs to form large bulbs.
What You’ll Need:
- Deep container: At least 10–12 inches deep to allow proper root growth.
- Drainage: Garlic hates sitting in soggy soil, so choose a pot with plenty of drainage holes.
- Soil mix: Use a rich, loose mix with compost and a handful of organic amendments such as bone meal or kelp meal.
Planting Tips:
- Clove spacing: Plant cloves 4–6 inches apart, pointed side up, 2 inches below the soil surface.
- Cold requirement: Garlic needs a long cold period (vernalization). If your containers are outdoors, let them freeze over the winter
- Watering: Keep soil moist but not waterlogged, especially in spring as shoots emerge.
Winter in Zones 3–5:
- Containers freeze more quickly than ground soil. Wrap pots in straw, burlap, or leaves, or sink them halfway into the ground for insulation.
- In the coldest zones (3–4), it’s often best to use a hardneck variety like Music, German Extra Hardy, or Northern White, which thrive in Alaska-like conditions.
Harvest:
- Garlic planted in fall will be ready the following summer. You’ll also get scapes (flower stalks) in July, which can be cut and eaten before the bulbs mature.
Bottom line: Garlic thrives in containers if you use a deep pot, protect it through the freeze-thaw cycles, and choose hardy varieties suited to northern zones.

When should I plant garlic in Alaska?
Plant garlic in fall when soil is 40–50°F, usually late September to mid-October. This allows roots to develop before the ground freezes.
