Washoe County, Nevada is in USDA Zone 7b. The average last spring frost is April 15 and the first fall frost is October 27, giving you a growing season of approximately 195 days.

At an elevation of 6,078 feet, Washoe County receives approximately 13.4 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 98°F, so Aronia may need afternoon shade and extra watering during peak heat. 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 ~21,444 GDD — county provides 4,582 GDD May not mature
