Crape Myrtle
Lagerstroemia indica
shrubCrape Myrtle is a deciduous to semi-evergreen ornamental shrub or small tree prized for its vibrant summer flowers in shades of pink, red, purple, or white. Known for its exfoliating bark that reveals attractive mottled trunks and brilliant fall foliage, it's a heat and drought-tolerant landscape staple in warm climates. The delicate, crepe-like petals give the plant its distinctive common name.

Establishment
4-8 weeksYoung bare-root or container plant with minimal branching and fresh buds breaking. New growth emerges as soft, reddish foliage.
Water consistently to keep soil moist but not waterlogged. Stake tall specimens to prevent wind damage. Avoid fertilizing immediately after planting.
Vegetative Growth
Spring through early summer, 8-12 weeksRapid stem elongation with leafy branches forming a rounded canopy. Glossy, oval leaves are burgundy when young, then mature to green. Plant may reach 50-75% of final height.
Prune only to remove crossing branches or maintain shape; heavy pruning reduces flowering. Deadhead spent flower clusters to encourage more blooms. Light fertilizing with balanced NPK in late spring.
Flowering
June through September, 6-12 weeks (or longer with deadheading)Terminal panicles of wrinkled, crepe-like flowers appear in clusters at branch tips. Colors range from white, pink, red, to deep purple depending on variety. Blooms may repeat if deadheaded.
Remove spent flower clusters to stimulate repeat blooming. Maintain consistent moisture; drought stress reduces flowering. Apply low-nitrogen fertilizer to boost blooms.
Maturation & Fall Color
September through November, 8-10 weeksFlowering slows as temperatures drop. Foliage transitions to brilliant shades of orange, red, or purple before dropping. Seed pods develop; ornamental bark becomes increasingly visible as leaves fall.
Discontinue fertilizing after August to allow hardening off. Do not prune heavily in fall. Leave seed pods and bark for winter interest. Avoid 'crape murder' (severe cutting that disfigures the plant).
Dormancy
December through March, 12-14 weeksBare branches display attractive exfoliating bark in shades of tan, gray, cinnamon, or cream. Tree stands bare and sculptural. No active growth.
Minimal care needed. Light pruning to remove dead wood, crossing branches, or weak growth is acceptable in late winter before new growth breaks. Avoid heavy pruning.

Common Pests
-
Hand-pick early morning, use pheromone traps, or apply neem oil. Avoid broad-spectrum insecticides that harm beneficial insects.
-
Spray with strong water stream to dislodge, use insecticidal soap, or release ladybugs. Usually not severe enough to require treatment.
-
Improve air circulation through proper pruning. Apply sulfur-based fungicide or baking soda spray (1 tbsp per gallon water) in early morning or evening. Water at soil level to keep foliage dry.
-
Prune infested branches, apply horticultural oil in late fall or early spring, or use insecticidal soap. Monitor new growth in spring.
-
Increase humidity and spray foliage with water. Use miticide if severe; neem oil may help. More common in hot, dry conditions.

Harvest Tips
Crape Myrtle is ornamental, not harvested. However, deadhead spent flower panicles (pinch off faded blooms) throughout the growing season to encourage repeat blooming. Cut at the base of the flower cluster, just above a leaf node. Collect seed pods in fall if desired for dried arrangements.
Fun Facts
- 🌱 The name 'crape myrtle' is derived from the delicate, crepe paper-like texture of the flowers, though the plant is not a true myrtle.
- 🌱 Crape myrtles can live for 50+ years and are beloved in Southern gardens; many historic specimens over 100 years old still thrive.
- 🌱 The exfoliating bark serves as a natural pest deterrent and is one of the plant's most attractive winter features, making it a four-season ornamental even after leaves drop.
