Care Instructions

Light: Full sun to light shade; afternoon shade is beneficial in Phoenix, especially for young plants. Avoid hot west-facing walls.

Water: Moderate water in Phoenix; irrigate deeply, then allow the upper several inches of soil to dry. Water more frequently during establishment and extreme summer heat; avoid constantly wet soil.

Soil: Well-drained sandy loam or loam; tolerates alkaline soil and clay if drainage is adequate. Apply mulch while keeping it away from the trunk.

Mature size: Typically 20–40 feet tall and 10–20 feet wide; dwarf cultivars remain substantially smaller.

Bloom: No true flowers; produces small pollen cones in late winter to spring and seed cones that mature later in the year.

Evergreen / deciduous: Evergreen.

Growth rate: Slow to moderate, depending on cultivar, irrigation, and growing conditions.
