Establishment (Young Tree)
6-12 monthsTree is 1-3 feet tall with developing canopy; produces minimal fruit as energy focuses on root development and branch structure
Water consistently, stake for support if needed, apply light pruning to shape, avoid heavy fertilizing to prevent salt burn, remove first-year flowers to encourage rooting
Vegetative Growth
12-24 monthsTree grows vigorously, developing dense foliage with glossy green leaves; canopy becomes fuller and more defined
Continue regular watering, apply balanced citrus fertilizer every 4-6 weeks during growing season, prune to maintain shape and open canopy for air circulation, monitor for pests
Flowering

Maintain consistent watering during flowering, apply phosphorus-rich fertilizer to encourage blooms, avoid pruning during heavy flowering, ensure good air circulation
Fruiting
Continuous, 4-6 months from flower to mature fruitSmall green fruits develop from flowers and gradually enlarge; fruit matures to bright orange color over several months; multiple fruit stages visible simultaneously
Maintain consistent watering and moisture, apply potassium-rich citrus fertilizer, thin excess fruit if desired for larger individual oranges, protect from strong winds, monitor for fruit-feeding pests
Harvest Maturity
Year-round, ongoingFruits are bright orange, 2-3 inches in diameter, with fragrant citrus aroma; sweet juice content is high; tree typically has fruit at various maturity stages simultaneously
