Care Instructions
Light: Full sun to light afternoon shade. In Phoenix, provide at least 6 hours of sun, preferably morning sun, with protection from intense western exposure and reflected heat.
Water: Water deeply, then allow the upper 2–3 inches of soil to dry before watering again. Increase frequency during extreme summer heat; reduce in winter. Containers need more frequent checks. Avoid constantly wet soil.
Soil: Well-drained loam or sandy loam. Tolerates mildly alkaline soil, but Phoenix soils may cause iron deficiency. Keep the root flare above grade and mulch without covering the trunk.
Mature size: Typically 8–12 feet tall and 6–10 feet wide in the ground; smaller on dwarfing rootstock or in containers.
Bloom: Fragrant flowers appear mainly in late spring and summer, sometimes in multiple flushes. Fruit generally ripens from winter into spring.
