Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings emerge with cotyledons and first true leaves appearing

Maintain high humidity and consistent moisture. Provide bright, indirect light. Keep soil warm (70-75°F). Thin seedlings to prevent damping off.

2

Vegetative Growth

4-6 weeks

Plant develops bushy foliage with multiple stems and leaves; no flowers yet

Pinch back growing tips to encourage branching. Fertilize every 2 weeks with balanced fertilizer. Ensure adequate light and consistent moisture.

3

Bud Formation

2-3 weeks

Flower buds begin appearing at stem tips; plant becomes more compact

Switch to fertilizer higher in phosphorus to promote flowering. Continue regular watering and maintain full sun exposure.

4

Flowering

6-12 weeks or more

Vibrant scarlet or crimson tubular flowers open in succession along stems

Deadhead spent blooms to encourage continuous flowering. Maintain consistent watering and fertilizing schedule. Watch for pests attracted to flowers.

5

Maturity & Decline

Ongoing through season

Plant may produce seed pods if not deadheaded; flowering slows in cooler months

In frost-prone areas, prepare to bring container plants indoors or treat as annual. Collect seeds if desired. Reduce watering and fertilizing.
