Growth Stages

1

Establishment

2-4 weeks

Young transplant with small stems and developing root system

Water regularly to keep soil moist. Provide protection from harsh sun and wind. Avoid fertilizer stress.

2

Vegetative Growth

4-8 weeks

Bushy plant with dense green foliage expanding in height and width

Prune to encourage branching and bushier form. Fertilize monthly with balanced or slightly higher phosphorus blend. Continue regular watering.

3

Budding

2-3 weeks

Flower buds visible at branch tips; plant continues to grow but flowering is imminent

Maintain consistent moisture and warmth. Apply higher phosphorus/potassium fertilizer to support blooming. Reduce nitrogen slightly.

4

Flowering

3-6 months (spring through fall in warm climates; year-round in tropical regions)

Abundant clusters of small, bright red flowers opening continuously throughout the season

Deadhead spent flowers to encourage continuous blooming. Water regularly, as flowering requires energy. Fertilize every 2-3 weeks with bloom-promoting fertilizer.

5

Dormancy/Rest

2-4 months

Reduced flowering and slower growth during cooler months; foliage remains evergreen

Reduce watering frequency. Minimize or stop fertilizing. Light pruning to shape the plant. Protect from temperatures below 50°F.
