Growing Garlic in Zone 4A

Garlic is planted in fall and harvested in summer. It’s one of the most rewarding low-maintenance crops.

Zone 4A has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• Plant individual cloves in fall, 6 weeks before ground freezes
• Hardneck varieties for cold climates (zones 3-6), softneck for warm (zones 7+)
• Mulch heavily after planting to protect through winter
• Cut scapes (flower stalks) in spring to redirect energy to bulbs
• Harvest when lower 1/3 of leaves have browned

Companion Planting

Good companions: tomatoes, roses, fruit trees, beets

Avoid planting near: beans, peas, asparagus

Harvest Timeline

8-9 months from fall planting
