Prof. Martin Thorne, Ph.D.Garlic planted at the right time determines the likelihood of successful growth. Knowing your local climate allows you to determine the optimal time of year for planting, whether in the fall or early spring. Having soil temperature is the best indicator for ideal timing. I always check at a depth of 4 inches.
Soil Temperature
- Measure consistently at 4 inch depth
- Ideal range: 45-55°F (7-13°C)
- Use digital probe thermometer for accuracy
Frost Dates
- Plant 4-6 weeks before first hard frost
- Roots establish before winter dormancy
- Avoid frozen ground conditions
Regional Variations
- Cold zones: late September to October
- Mild zones: November to December
- Warm zones: January to February
Fall planting gives cloves time to grow roots before winter. Spring leads to stronger plants. I generally plant when the leaves in my area are beginning to change color. Spring planting is well-suited for areas with mild winters. Refrigerate the cloves before planting to simulate winter chill.
Each year, I observe the weather patterns. Early-season frosts require faster plantings. Warm fall weather lengthens your planting period. I keep a journal of temperatures around my garden. This helps me determine when to plant my plots best. Your extension office also has valuable resources.
