Transplant Establishment
4-8 weeksYoung shrub settling into garden with new growth emerging
Water regularly to establish deep roots; apply 2-3 inches of mulch around base. Prune only to remove damaged branches initially.
Spring Growth & Color Change
4-6 weeksNew foliage emerges in red-bronze tones; branches elongate with fine, delicate leaves
Remove any winter-damaged wood. Light pruning to shape can be done now. Watch for early pest activity.
Summer Flowering
6-8 weeksFoliage transitions to golden-yellow; clusters of small pink flowers appear on branch tips
Maintain consistent moisture during flowering. Deadhead spent flowers to encourage longer bloom period. Foliage color may fade if in partial shade.
Late Summer to Fall Transition
6-8 weeksFlowers fade; foliage shifts to orange-red tones as temperatures cool
Reduce watering slightly as growth slows. This is a good time for major pruning if needed (prune to 12 inches in late winter for renewal).
Dormancy
12-14 weeksLeaves drop; bare branches remain attractive with reddish tones visible on stems
No watering needed during dormancy (except in severe drought). Major rejuvenation pruning can be done in late winter before spring growth.
