Deutzia is a reliable flowering shrub for Middle Tennessee that delivers a heavy spring bloom display and otherwise requires minimal maintenance. The primary pruning requirement is thinning out the oldest, most congested canes immediately after bloom in June — deutzia blooms on previous year's wood, so pruning in late fall or winter removes the next season's flower buds. Rejuvenation by removing one-third of the oldest canes each year over three years maintains an open, productive framework. In Middle Tennessee's humid climate, deutzia has low disease susceptibility compared to other spring-flowering shrubs, though powdery mildew can affect foliage in low-airflow interior plantings by August. Scale insects occasionally infest canes; dormant oil applied before bud break controls most scale populations. Deer browse the soft new growth in spring in areas with high deer pressure.
