Care Instructions

Light: Full sun to light shade; in Phoenix, favor morning sun with protection from intense afternoon heat and reflected heat.

Water: Moderate to high supplemental water in Phoenix. Irrigate deeply throughout the root zone, allowing the upper few inches of soil to dry between waterings. Increase watering frequency during extreme summer heat; avoid constantly wet soil.

Soil: Well-drained loam preferred; tolerates other soil textures if drainage is adequate. Alkaline Phoenix soils may cause iron chlorosis. Apply organic mulch, keeping it away from the trunk.

Mature size: Typically 15–25 feet tall and 15–25 feet wide, depending on cultivar and conditions.

Bloom: Late winter to early spring, usually before or as leaves emerge; flowering varies with cultivar and winter temperatures.

Evergreen / deciduous: Deciduous.

Growth rate: Moderate to fast with adequate water; slower under heat or water stress.
