Growth Stages

1

Establishment

3-4 weeks

Young transplants developing root systems and branching structure with initial leaf formation

Water regularly to keep soil moist; pinch back growing tips once plant is established to encourage bushier growth and more flower buds

2

Vegetative Growth

6-8 weeks

Plant develops sturdy stems and abundant foliage; no visible flower buds yet

Continue pinching back stems through mid-August to encourage branching (stop pinching by late August); fertilize every 2-3 weeks with balanced or slightly higher phosphorus formula; provide support stakes if needed

3

Bud Formation

3-4 weeks

Flower buds begin to form at stem tips; plant structure is fully developed

Stop pinching plants; maintain consistent watering; switch to higher phosphorus fertilizer to encourage flowering; remove any diseased or damaged stems

4

Flowering

4-6 weeks

Large, layered chalice-shaped blooms open with distinctive white petals and salmon-pink petal margins; flowers are fully double and impressive

Continue regular watering; deadhead spent blooms to encourage more flowers if needed; stake plants if flowers cause stems to bow; provide afternoon shade in hot climates to preserve color

5

Senescence & Dormancy

4-8 weeks depending on climate

Flowering declines as temperatures drop and days shorten; foliage may yellow; plant prepares for winter

Reduce watering; cut back dead stems to 3-4 inches above ground after hard frost; add 3-4 inches of mulch in cold zones; avoid cutting too early in mild climates where foliage provides winter protection
