Santa Cruz County, Arizona is in USDA Zone 8b. The average last spring frost is March 30 and the first fall frost is November 7, giving you a growing season of approximately 222 days.

At an elevation of 4,351 feet, Santa Cruz County receives approximately 8.1 inches of rainfall annually with predominantly sandy loam soil.

Medlar 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.

Medlar needs ~36,500 GDD — county provides 5,550 GDD May not mature
