Growth Stages

1

Establishment

2-4 weeks

New transplants settle in with initial leaf growth and root development

Keep soil consistently moist for first 2-3 weeks. Mulch around base, leaving stem area clear. Plant in spring or early fall for best establishment.

2

Vegetative Growth

6-8 weeks

Stems elongate and leaf count increases; plant develops bushy form

Water regularly and apply balanced fertilizer monthly. Pinch back stem tips by ½ inch in late spring to encourage branching and fuller plant shape.

3

Bud Formation

3-4 weeks

Flower buds appear at stem tips; plant reaches near full height

Continue regular watering. Ensure good air circulation to prevent fungal disease. Stake tall varieties if needed. Reduce nitrogen fertilizer to encourage flowering.

4

Blooming

6-8 weeks

Dense panicles of soft pink flowers open progressively from bottom to top; fragrant display

Deadhead spent flowers to extend bloom period 2-4 weeks. Ensure consistent watering during heat. Monitor for powdery mildew; water at soil level only.

5

Decline & Dormancy

4-6 weeks through winter

Flowers fade, foliage yellows, plant enters senescence in fall

Cut back stems to 4-6 inches after first frost or in late fall. Leave some dried stems over winter for wildlife shelter. Mulch around base for winter protection in colder zones.
