Growth Stages

1

Seedling/Establishment

4-6 weeks

Young plants develop their first true leaves and establish root systems. Growth is slow initially.

Keep soil warm (70-80°F), maintain high humidity, provide bright indirect light, and avoid overwatering. Protect from wind.

2

Vegetative Growth

8-12 weeks

Plant develops branching stems, larger leaves, and a fuller canopy. No flowers yet.

Pinch growing tips to encourage bushiness. Provide full sun, consistent moisture, and balanced fertilizer (10-10-10) every 2-3 weeks. Support with stakes if needed.

3

Bud Formation

4-6 weeks

Small flower buds appear at branch tips. Plant structure becomes more defined.

Switch to higher phosphorus fertilizer (5-10-10) to promote flowering. Maintain full sun exposure and consistent watering. Ensure good air circulation.

4

Flowering

6-12 weeks or until frost

Large, vibrant deep red flowers with prominent centers open. Blooms may last 1-2 days each but are produced continuously.

Continue regular watering and fertilizing every 2 weeks. Deadhead spent flowers to encourage more blooms. Monitor for pests attracted to flowers.

5

Dormancy/Winter

3-4 months

Growth slows significantly or stops in cool winter conditions. Leaf drop may occur in zone 9.

Reduce watering and fertilizing. In zones 9a-9b, provide frost cloth or move containers to sheltered locations. Prune dead wood in early spring. Temperature below 50°F stresses the plant.
