Establishment
1-2 yearsYoung tree (1-2 years old) focuses on root and canopy development with minimal flowering
Stake for support, remove early flowers to direct energy to growth, water consistently, apply light mulch
Vegetative Growth
1-2 yearsTree develops dense, compact foliage with increasingly vigorous branching
Light pruning to shape, continue consistent watering and fertilizing during growing season (spring-summer), remove any competing leaders
Flowering
4-8 weeks per bloom cycleAbundant fragrant white flowers appear in spring (late March-April), often with some reflowering in summer
Maintain consistent moisture and warmth, provide phosphorus-rich fertilizer, avoid over-pruning, hand-pollinate if indoors or in low-bee-activity areas
Fruit Development
3-4 monthsSmall marble-sized fruits develop from pollinated flowers, gradually enlarging over 3-4 months
Thin excessive fruit set if needed (thin to 1 fruit per 6-8 inches of branch), maintain even watering and potassium-rich fertilizer, protect from wind stress
Ripening & Harvest
