Growth Stages

Establishment

First 3-6 months

Newly planted shrub with limited growth, developing root system

Water regularly to keep soil consistently moist. Apply 2-3 inches of mulch around base, keeping away from stem. Avoid fertilizing first year.

Vegetative Growth

Spring through summer

Rapid branching and shoot development; golden-yellow foliage emerges bright and vibrant

Maintain regular watering schedule. Prune lightly in late winter to shape and encourage bushier growth. Golden color most intense in full sun.

Flowering

Late May through June

Small white-to-pale-pink flowers appear in terminal clusters along branches

Flowers are self-pollinating and attractive to pollinators. No deadheading needed unless appearance is a concern. Blooms do not significantly detract from foliage display.

Fruiting & Color Change

July through fall

Decorative reddish seed pods develop; foliage intensifies to deep orange-red as temperatures cool

Leave seed pods on plant for ornamental interest and wildlife food. Autumn color is most dramatic after first frost. Prune out any dead or crossing branches.

Dormancy

November through February

Leaves drop; exfoliating bark becomes prominent architectural feature with multi-colored peeling texture

Dormant season is ideal time for structural pruning. Prune immediately after winter while buds have not yet broken. Do not fertilize during dormancy.
