Care Instructions

Light: Full sun for best fruiting; in Phoenix, provide at least 6 hours of sun with protection from intense late-afternoon summer exposure.

Water: Moderate to high water needs in Phoenix. Water deeply throughout the root zone, allowing the upper few inches of soil to dry between irrigations. Increase frequency during extreme heat; reduce watering during winter dormancy.

Soil: Deep, well-drained loam preferred. Avoid waterlogged soil and heavily compacted sites. Apply organic mulch over the root zone, keeping it several inches away from the trunk.

Mature size: Typically 15–25 feet tall and wide on standard rootstock; smaller on dwarfing rootstock or with regular pruning.

Bloom: Late winter to early spring, depending on winter temperatures. Fruit generally ripens in late spring to early summer in warm climates.

Evergreen / deciduous: Deciduous.

Growth rate: Moderate to fast with adequate irrigation and suitable soil.
