Sonoran Emerald

Light: Full sun; thrives in Phoenix heat with adequate room for canopy development.

Water: Low water once established. Water deeply throughout the root zone, then allow soil to dry between irrigations. In Phoenix, established trees generally benefit from deep watering every 2–4 weeks during summer; reduce watering substantially in cooler months. Water new trees more frequently.

Soil: Well-drained sandy, gravelly, or loamy soil. Tolerates alkaline desert soils; avoid persistent moisture and poorly drained planting sites.

Mature size: Approximately 25–30 feet tall and wide, depending on growing conditions and pruning.

Bloom: Primarily spring, sometimes extending into early summer; timing and abundance vary with weather and irrigation.

Evergreen / deciduous: Semi-evergreen; may shed foliage during drought or cold weather.

Growth rate: Fast with supplemental irrigation; slower under very dry conditions.
