Growing garlic in zone 7b
Zone 7b has an average last spring frost around Apr 5 and a first fall frost around Nov 1, giving roughly 210 frost-free growing days. That window comfortably fits garlic's 240-day cycle, so plant on time to make the most of the season.
Garlic resents transplanting, so direct sow it right in the garden around Sep 20. Give each plant about 6 inches of space in full sun.
Zone 7b specific growing notes
In zone 7b (Atlanta GA, Raleigh NC), your 210-day growing season means garlic should be one of your first spring plantings. Cool-season crops thrive in the mild part of your growing window. Monitor soil temperature — garlic germinates best when soil is 40-75°F.
Your first fall frost around Nov 1 means your last possible harvest is roughly late Nov. For a continuous supply, consider planting early and using season extension techniques like row covers.
Pro tip for garlic
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.
Can you plant garlic twice a year?
No—garlic is planted in fall (October-November) and harvested the following summer (July), an 8-9 month cycle. It occupies the bed for nearly a year, so plan space accordingly.
