Catron County, New Mexico is in USDA Zone 6a. The average last spring frost is June 3 and the first fall frost is September 22, giving you a growing season of approximately 111 days.

At an elevation of 8,232 feet, Catron County receives approximately 10.4 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 83°F, so choose short-season varieties of Leeks to ensure they mature before fall. Sandy soil warms quickly in spring — great for early planting — but Leeks will need more frequent watering and organic matter to retain nutrients. With low rainfall, drip irrigation is essential for growing Leeks successfully. Mulch heavily to conserve soil moisture.
