Growth Stages

1

Establishment

2-3 weeks

Young transplants with initial leafy growth and root development

Plant after last frost; ensure consistent moisture without waterlogging. Pinch growing tips once to encourage bushier growth.

2

Vegetative Growth

6-8 weeks

Plant develops dense foliage and multiple branching stems; no flowers yet

Pinch back stem tips every 2-3 weeks until late July/early August to create compact, bushy plants with more flower buds. Fertilize every 2 weeks with balanced fertilizer.

3

Bud Formation

3-4 weeks

Flower buds appear at branch tips as day length shortens in late summer

Stop pinching plants; allow buds to develop. Switch to lower-nitrogen, higher-phosphorus fertilizer to encourage blooming. Maintain consistent watering.

4

Flowering

4-8 weeks

Abundant blooms in fall colors covering much of the plant; flowers open progressively over weeks

Deadhead spent flowers to encourage continued blooming. Water at base only to keep flowers dry and prevent disease. Stake tall varieties if needed.

5

Decline and Dormancy

2-4 weeks before dormancy

Flowers fade and plant enters dormancy; foliage may yellow or brown

In cold climates, cut stems back to 3-4 inches after hard frost. Apply 2-3 inches of mulch for winter protection. In mild climates, may remain evergreen; prune lightly.
