Is Garlic right for your USDA zone?
Garlic is a cool-season crop, which means it thrives in the mild temperatures of spring and fall. Gardeners in zones 3a through 7b get the longest garlic season — you can plant in early spring and again in late summer for a fall harvest. In warmer zones (8a-10b), grow garlic as a winter crop from October through February when temperatures are coolest.
Garlic needs about 240 days from sowing to harvest, so any zone with at least 254frost-free days can grow it successfully. Check your zone's specific dates in the table below.
How to grow garlic
Garlic grows best when direct-sown right where it will mature, because it dislikes having its roots disturbed. Give each plant 6 inches of room in full sun, and keep the soil consistently moist while seeds germinate and plants establish.
Expect roughly 240 days to your first harvest. Watch for onion maggot, rust, the most common pests of garlic, and scout plants weekly so you can act early. Crack bulbs and plant individual cloves pointy-side up, 2 inches deep and 6 inches apart. The largest cloves produce the largest bulbs—save the biggest for planting, cook with the small ones.
Troubleshooting garlic
Garlic rust appears as orange-brown powdery spots on leaves. It spreads in humid conditions with poor airflow. Space plants adequately, avoid overhead watering, and remove infected leaves promptly.
Growing garlic in containers
6-inch deep containers work with 4-inch spacing between cloves. A 5-gallon grow bag holds 8-10 plants. Mulch heavily with straw after planting for winter insulation in zones 3-6.
