Growth Stages

1

Establishment

4-8 weeks

Young seedling or transplant develops initial root system and foliage; plant is small with tender growth

Keep soil consistently moist; provide bright, indirect light; protect from wind; apply light mulch around base

2

Vegetative Growth

3-6 months

Plant expands, developing dense foliage and branching structure; no flowers yet

Maintain even moisture; fertilize monthly with balanced fertilizer; pinch back growing tips to encourage bushiness; ensure good air circulation

3

Flowering

Continuous in warm climates, primary blooms spring-summer (3-4 months peak)

Plant produces abundant small white trumpet flowers in clusters; flowers bloom throughout the year in warm climates, heavily in spring and summer

Reduce nitrogen fertilizer; apply phosphorus-rich fertilizer to promote blooms; deadhead spent flowers to encourage more blooms; maintain consistent watering and humidity

4

Fruiting

2-3 months

After pollination, small berry-like fruits develop; fruits are orange or red when mature

Allow some flowers to remain unpollinated for fruit development if desired; fruits can be left on plant or removed; minimize fertilizer

5

Dormancy/Maintenance

Varies by climate; 2-3 months in subtropical regions

In cooler months (if temperatures drop below 65°F), growth slows and flowering decreases; plant remains mostly evergreen

Reduce watering slightly; hold off on heavy fertilizing; prune for shape if needed; protect from cold drafts and temperatures below 50°F

Harvest Tips

Pick flowers in early morning when fragrance is strongest and blooms are fully open but still fresh. Use sharp, clean scissors or pruning shears. Cut at the base of the flower cluster or stem. Flowers are best used immediately but can be chilled for a few hours. For lei-making, harvest flowers with 2-3 inches of stem for stringing.
