Growth Stages

1

Seedling

4-6 weeks

Tiny seedlings emerge with two small cotyledons; develop first true leaves within 3-4 weeks

Keep soil consistently moist; provide bright indirect light; protect from direct sun and strong air currents; maintain high humidity

2

Establishment

3-6 months

Young plant develops deeper root system and second set of true leaves; growth is slow and steady

Continue consistent watering; apply balanced fertilizer monthly; provide partial shade; avoid transplanting until 6-8 inches tall

3

Vegetative Growth

6-18 months

Shrub develops more branching structure and fuller foliage; narrow leaves become more prominent

Fertilize monthly during growing season; prune lightly to encourage bushiness; maintain consistent moisture and partial shade

4

Pre-flowering

2-4 months

Plant reaches sufficient maturity; stems begin to harden; buds start to form at branch tips

Reduce nitrogen fertilizer; provide slightly cooler winter conditions if possible; maintain good air circulation

5

Flowering & Fruiting

Ongoing once mature

Fragrant small white flowers appear in clusters; flowers followed by small fruit; may bloom intermittently year-round in tropical conditions

Continue regular watering and partial shade; deadhead spent flowers to encourage more blooms; hand-pollinate if needed
