When to Plant Garlic in Taos County, NM
Garlic is a pungent allium planted in fall and harvested the following summer. Hardneck varieties produce edible flower stalks (scapes) and are more cold-hardy.
Taos County, New Mexico is in USDA Zone 5a. The average last spring frost is May 26 and the first fall frost is September 21, giving you a growing season of approximately 118 days.
At an elevation of 7,833 feet, Taos County receives approximately 17.8 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 85°F, providing good warmth for Garlic during the growing season. Sandy soil warms quickly in spring — great for early planting — but Garlic will need more frequent watering and organic matter to retain nutrients. With low rainfall, drip irrigation is essential for growing Garlic successfully. Mulch heavily to conserve soil moisture.

Garlic Heat Requirements (GDD)
What are Growing Degree Days (GDD)?
Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.
Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.
