Establishment
First 12 monthsNewly planted shrub with emerging leaves and developing root system; growth may be modest in first year
Water regularly and deeply; apply 2-3 inches of mulch around base; avoid fertilizing the first year; provide afternoon shade in hot climates
Vegetative Growth
Year 2-4Vigorous expansion of stems and deeply lobed foliage; new shoots emerge from base and branches; distinctive oak-shaped leaves fully developed
Water consistently; apply balanced slow-release fertilizer in spring; mulch to conserve moisture; prune only to shape if needed; monitor for pests
Flowering
June-August (6-8 weeks)Tall, cone-shaped white flower panicles emerge from branch tips; flowers are sterile and long-lasting, aging to pink then tan
Maintain consistent moisture; deadhead spent flowers to encourage neater appearance; do not prune during flowering season; flowers last 8-10 weeks
Fall/Winter Transition
September-NovemberFoliage transitions to bronze and burgundy; leaves may persist through winter; exfoliating bark becomes more prominent and attractive
Reduce watering frequency; avoid pruning until late winter; leave dried flower panicles for winter interest if desired; apply fall mulch refresh
Dormancy
December-MarchShrub enters dormancy with bare or semi-persistent stems; attractive peeling bark is most visible; plant is cold-hardy and requires minimal care
No watering needed in winter (unless in severe drought); avoid pruning tender new growth if mild spells occur; spring pruning can be done in late February to March
