When to Plant Rue in Greenlee County, AZ

Rue is a bitter, aromatic perennial herb with bluish-green foliage used historically in medicine and as a pest deterrent. Handle with care as its sap can cause skin irritation.

Greenlee County, Arizona is in USDA Zone 7a. The average last spring frost is April 22 and the first fall frost is October 22, giving you a growing season of approximately 183 days.

At an elevation of 4,156 feet, Greenlee County receives approximately 14.4 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 95ยฐF, so Rue may need afternoon shade and extra watering during peak heat.

With low rainfall, drip irrigation is essential for growing Rue successfully. Mulch heavily to conserve soil moisture.
