Growth Stages

1

Establishment

Spring to early summer (8-10 weeks)

Young plants develop basal foliage and establish root systems

Water regularly, provide stake support if needed. Remove any flower buds first season to encourage root development.

2

Vegetative Growth

Late spring to mid-summer (6-8 weeks)

Stems elongate and foliage fills out; plants develop into bushy clumps

Pinch back stems in early June for bushier growth and more flowers. Apply balanced fertilizer monthly. Ensure consistent watering.

3

Flowering

Mid-summer to early fall (8-12 weeks)

Dense panicles of pale pink flowers with red centers open from bottom to top of flower clusters

Deadhead spent blooms regularly to encourage continued flowering. Water deeply during dry spells. Support tall stems with stakes if needed in windy locations.

4

Decline

Fall (4-6 weeks)

Flowering slows as temperatures cool; foliage may show signs of disease or yellowing

Continue deadheading if repeat blooms desired. Improve air circulation to prevent powdery mildew. Reduce watering slightly as growth slows.

5

Dormancy

Winter (3-4 months)

Foliage dies back after frost; plant is dormant underground

Cut back stems to 2-3 inches above ground in late fall or early spring. Mulch 2-3 inches deep for winter protection in colder zones. No watering needed.
