Seedling
4-6 weeksYoung plants with 2-4 true leaves, tender growth with thin stems and small leaflets
Maintain consistent moisture without waterlogging. Provide bright indirect light. Protect from strong winds. Keep soil warm (70-80°F optimal).
Vegetative Growth
1-2 yearsEstablishment of main trunk and branch structure; developing compound leaves and expanding canopy
Water regularly during dry spells. Apply balanced slow-release fertilizer monthly during growing season. Prune to shape and remove weak branches. Mulch around base to retain moisture.
Pre-flowering
4-6 weeks before floweringTree reaches mature size with dense foliage; small flower buds begin forming on branch terminals
Reduce nitrogen fertilization to encourage flowering. Maintain consistent watering. Remove any damaged or crossing branches. Apply mulch to conserve moisture.
Flowering
4-8 weeks (spring to early summer typically)Small, fragrant flowers appear in clusters; flowers are typically white to pale yellow and attract pollinators
Maintain moderate watering; avoid waterlogging which may cause flower drop. Do not heavily prune during this period. Pollination is enhanced by bees and other insects.
Fruiting & Harvest
8-12 weeks from fruit set to maturitySmall drupes develop and change color from green to red, then dark purple-black when fully ripe; fruits 0.3-0.5 inches in diameter
Continue regular watering to support fruit development and size. Thin crowded fruit if desired for larger individual fruits. Harvest ripe fruits regularly to encourage continued production.
