Growth Stages

1

Seedling

2-3 weeks

Tiny green shoots with first true leaves; very delicate

Keep soil moist, provide bright light, maintain 65-70°F for germination. Use grow lights if indoors. Thin seedlings to proper spacing.

2

Vegetative Growth

4-8 weeks

Bushy plant with multiple stems and dense foliage; no flowers yet

Pinch back stem tips in early summer to encourage bushier growth and more flower buds. Water regularly. Apply balanced fertilizer every 3-4 weeks.

3

Budding & Early Flowering

2-3 weeks

Small flower buds appear at stem tips; first pink flowers open

Continue watering consistently. Switch to low-nitrogen fertilizer to promote blooms. Remove any diseased leaves immediately. Stake tall varieties if needed.

4

Peak Flowering

6-10 weeks

Abundant pink flowers with yellow centers covering the plant; profuse blooming

Deadhead spent flowers to extend bloom time. Water deeply but avoid wetting foliage. Monitor for powdery mildew and spider mites. Apply light fertilizer if needed.

5

Decline & Winter Dormancy

8-12 weeks

Flowers fade as temperatures drop; foliage dies back in fall/winter

Cut back stems to 3-4 inches after hard frost. Apply 2-3 inches of mulch for winter protection. In spring, remove mulch and old growth to allow new shoots.
