Growth Stages

1

Establishment

2-3 months

Young plant developing root system and initial foliage growth; small glossy leaves emerging

Keep soil moist, provide indirect light, protect from strong winds, maintain warmth (70-80°F). Do not fertilize heavily in first months

2

Vegetative Growth

6-12 months

Plant producing new stems and dense foliage; becoming bushy with characteristic dark green, glossy leaves arranged in whorls

Pinch back tips to encourage branching, maintain consistent moisture and humidity, apply balanced fertilizer monthly

3

Flowering

2-4 months (can repeat)

Fragrant, star-shaped white flowers (often tinged pink) blooming in clusters at branch tips, typically in spring to summer

Maintain warm temperatures and high humidity to maximize fragrance, reduce nitrogen fertilizer to encourage blooming, deadhead spent flowers to extend blooming

4

Fruiting

2-3 months

Small round berries developing, initially green then ripening to red; seeds viable for propagation

Maintain consistent watering during fruit development, provide light feeding, pollination may need hand assistance indoors

5

Dormancy/Resting

3-4 months (seasonal in tropics, or if temperature-stressed)

Reduced growth in winter months; plant slows metabolism in cooler temperatures

Reduce watering frequency, decrease fertilizing, maintain warmth (minimum 60°F), prune dead wood
