Care Instructions

Light: Full sun; allow ample space away from buildings and overhead utilities.

Water: Moderate water in Phoenix. Water deeply and regularly during establishment; established trees need supplemental deep irrigation during hot, dry weather. Irrigate broadly beneath and beyond the canopy, allowing soil to partially dry between waterings.

Soil: Well-drained soil; tolerates sandy, loamy, or clay soils if drainage is adequate. Highly alkaline or saline soils may cause nutrient deficiencies and reduced vigor.

Mature size: Typically 40–80 feet tall and 60–100 feet wide; often smaller in Phoenix, depending on irrigation, soil, and available rooting space.

Bloom: Small, inconspicuous flowers in spring, usually March–April.

Evergreen / deciduous: Broadleaf evergreen to briefly semi-evergreen; older leaves drop as new growth emerges in spring.

Growth rate: Moderate; faster when young with adequate irrigation, slower under desert stress.
