Growth Stages

Establishment

First year

Newly planted shrub developing root system and initial branch structure

Water regularly to keep soil moist. Avoid fertilizing first year. Mulch around base to retain moisture and regulate soil temperature.

Spring Growth

April-May

Vibrant orange-red new foliage emerges, providing striking color contrast

Apply balanced fertilizer as growth begins. This is the most colorful foliage stage. Prune any dead winter damage.

Summer Transition

June-July

Foliage gradually transitions from orange-red to golden-yellow then to green as season progresses

Continue regular watering. Light pruning can encourage bushier growth. Deadhead spent flowers if desired.

Flowering

June-August

Delicate pink flower clusters (corymbs) appear above the foliage

Flowers attract pollinators and beneficial insects. Leave some flowers for wildlife value. Can deadhead for tidier appearance.

Fall Dormancy

September-March

Foliage may develop reddish or orange tones before dropping; plant enters dormancy

Reduce watering as growth slows. Prune in late winter while dormant to shape plant and remove old wood. No fertilizer needed.
