Care Instructions

Light: Full sun, ideally 6–8 hours daily. In Phoenix, protect young trees from intense afternoon sun and reflected heat.

Water: Water deeply and regularly, allowing the upper few inches of soil to dry between irrigations. Increase frequency during extreme summer heat; irrigate broadly beneath and beyond the canopy, keeping the trunk dry.

Soil: Well-drained soil. Tolerates sandy or loamy soils but struggles with waterlogged clay or restrictive caliche. Plant with the root flare slightly above grade and keep the graft union above soil.

Mature size: Typically 15–25 feet tall and 12–20 feet wide on standard rootstock; dwarfing rootstocks and pruning can keep trees substantially smaller.

Bloom: Primarily late winter through spring in Phoenix; bloom timing varies with weather.

Evergreen / deciduous: Evergreen.

Growth rate: Moderate with adequate irrigation and citrus fertilization.
