Pomegranates are drought-tolerant shrubs or small trees producing fruits filled with jewel-like, sweet-tart arils. They thrive in hot, dry climates and make excellent hedges.

La Paz County, Arizona is in USDA Zone 9a. The average last spring frost is February 2 and the first fall frost is December 6, giving you a growing season of approximately 307 days.

At an elevation of 4,875 feet, La Paz County receives approximately 17.4 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 105°F, so Pomegranate may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Pomegranate will need more frequent watering and organic matter to retain nutrients. With low rainfall, drip irrigation is essential for growing Pomegranate successfully. Mulch heavily to conserve soil moisture.

Pomegranate 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.

Pomegranate needs ~26,234 GDD — county provides 8,855 GDD May not mature
