When to Plant Honeydew in Coconino County, AZ

Honeydew melons have smooth, pale green rinds and sweet, light green flesh. They require a long, warm growing season and are slightly more heat-tolerant than cantaloupe.

Coconino County, Arizona is in USDA Zone 5b. The average last spring frost is May 28 and the first fall frost is September 27, giving you a growing season of approximately 122 days.

At an elevation of 7,869 feet, Coconino County receives approximately 13.9 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 96ยฐF, so Honeydew may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Honeydew will need more frequent watering and organic matter to retain nutrients. With low rainfall, drip irrigation is essential for growing Honeydew successfully. Mulch heavily to conserve soil moisture.
