Dormancy
November-March (varies by zone)Bare branches without leaves; plant appears completely dormant during winter months
Prune in late winter/early spring before growth resumes; remove crossing branches, deadwood, and suckers. Avoid heavy pruning to maintain natural vase shape.
Leaf-out & Growth
April-JuneNew bronze to reddish leaves emerge along branches; vigorous vegetative growth phase
Provide consistent moisture; apply balanced fertilizer in spring. Monitor for early-season pests. Remove any winter-damaged branches.
Budding & Flowering
July-AugustTerminal panicles of deep purple-red flowers develop at branch tips; blooms appear in succession
Deadhead spent flowers to encourage reblooming. Maintain consistent watering. Fertilize monthly with lower-nitrogen formula to support blooms.
Extended Bloom & Rebloom
August-OctoberContinuous flowering as new flower clusters replace deadheaded blooms; some flowers persist while new ones form
Continue deadheading for maximum flower production. Monitor for spider mites in heat. Reduce supplemental watering if established.
Fall Decline & Dormancy Preparation
October-NovemberFoliage transitions to orange-red; flowers decrease; leaves drop; exfoliating bark becomes visible

Fun Facts
- 🌱 The name 'crape myrtle' comes from the crepe-like texture of the flowers, and the plant is not actually related to true myrtles despite its common name.
- 🌱 Catawba crape myrtles are named after the Catawba Native American people and were developed through careful breeding programs to be cold-hardy cultivars suitable for zones 6-7.
- 🌱 The exfoliating bark of mature crape myrtles reveals beautiful cinnamon, tan, and gray tones, providing striking winter interest; the bark naturally peels and should never be painted or artificially treated.
