Growth Stages

1

Establishment (First 4-8 weeks)

4-8 weeks

Young plant acclimating to new location with new leaf growth and root development

Water regularly to maintain consistent soil moisture; avoid full fertilization immediately; provide afternoon shade if temperatures exceed 90°F; avoid transplanting stress by handling gently

2

Vegetative Growth (2-6 months)

2-6 months

Plant develops dense foliage and branching structure with glossy dark green leaves

Apply balanced fertilizer monthly during warm season; prune to encourage bushiness; pinch back growing tips to promote branching; maintain consistent moisture

3

Flowering (6-12 months, recurring)

6-12 months (can bloom year-round in tropical climates)

Dense clusters of small star-shaped scarlet flowers appear at branch tips; clusters (flowers) are composite inflorescences

Continue regular watering and monthly fertilization; apply flower-promoting fertilizer (higher phosphorus); deadhead spent flowers to encourage continuous blooming; keep foliage dry when watering

4

Dormancy/Rest (Winter in subtropics)

2-4 months (depending on climate)

Growth slows significantly; flowering reduces or stops in cooler months; plant appears less vibrant

Reduce watering frequency; hold back fertilization; maintain bright light; protect from frost or move indoors if temperatures drop below 50°F; avoid pruning during this period

5

Renewal (Spring)

4-8 weeks

New vigorous growth emerges as temperatures warm; flowering resumes with intensity

Resume regular watering and monthly feeding; prune to remove winter damage or leggy growth; adjust spacing if needed; watch for pest emergence
