Aronia (chokeberry) is an extremely hardy native shrub producing astringent dark berries rich in antioxidants. The berries are typically processed into juice, jam, or wine.

Humboldt County, Nevada is in USDA Zone 6b. The average last spring frost is May 30 and the first fall frost is September 15, giving you a growing season of approximately 108 days.

At an elevation of 5,527 feet, Humboldt County receives approximately 8.2 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 94°F, providing good warmth for Aronia during the growing season. Sandy soil warms quickly in spring — great for early planting — but Aronia will need more frequent watering and organic matter to retain nutrients. With low rainfall, drip irrigation is essential for growing Aronia successfully. Mulch heavily to conserve soil moisture.

Aronia 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.

Aronia needs ~18,706 GDD — county provides 2,214 GDD May not mature
