Establishment
4-6 weeksYoung transplant with developing root system and 2-4 sets of leaves
Water regularly to maintain soil moisture; provide bright indirect light; protect from strong winds; avoid fertilizing for first 4 weeks
Vegetative Growth
3-6 monthsVigorous branch development with increasing foliage density and fuller shape
Water consistently; apply balanced fertilizer monthly; prune to shape if desired; increase light gradually; maintain high humidity
Pre-flowering
2-4 weeksBranch tips begin to thicken; leaf production slows relative to stem growth
Reduce nitrogen slightly; maintain consistent moisture; increase potassium and phosphorus; ensure adequate light for flower development
Flowering
4-8 weeksSmall yellow flowers appear in clusters at branch tips; sweet fragrance becomes noticeable
Maintain moisture without overwatering; avoid heavy pruning; continue regular fertilization; ensure good air circulation
Fruiting & Maturation
OngoingBerry-like fruits develop from flowers; foliage becomes denser and more ornamental
Water moderately; support heavy fruit with stakes if needed; allow some fruits to mature for seed dispersal; prune lightly after fruiting
