Growth Stages

Establishment

3-6 months

Young shrub focuses on root development and initial growth after transplanting

Water regularly (2-3 times weekly), provide afternoon shade in hot climates during first year, mulch base to retain moisture

Spring Growth

4-6 weeks

Bright red-orange new foliage emerges, contrasting sharply with older growth

Pruning can be done in late winter or early spring; thin out dead or crowded wood; prune to desired shape before growth accelerates

Summer Foliage & Flowering

8-10 weeks

Foliage transitions to golden-yellow; delicate pink flower clusters (panicles) appear in early to mid-summer

Maintain consistent moisture during blooming; deadhead spent flowers to encourage tidiness and potential reblooming; fertilize lightly with balanced fertilizer if soil is poor

Fall Color & Dormancy

6-8 weeks

Foliage turns bronze-red in fall before leaves drop; plant prepares for winter

Reduce watering as temperatures cool; no fertilizing; allow natural fall color display

Winter Dormancy

3-4 months

Deciduous shrub is leafless; stems provide structural interest; plant is fully dormant

No watering needed unless extended dry spell occurs; can prune during dormancy if needed; mulch protects shallow roots in colder zones
