Scarlet Crape Myrtle

Scarlet Crape Myrtle is admired for its brilliant scarlet-red blooms that cover the plant all throughout the summer. Its rich green leaves complement the vivid flowers, creating a stunning seasonal display. This tree grows 20 feet in height and 12 feet in width, with an upright and rounded growth habit, making it ideal for borders, hedges, or as a standout specimen. It attracts pollinators, bringing extra life to your bed.

• Deciduous tree
• Fast growth rate with upright, rounded habit
• Bright scarlet-red flowers all summer long
• Lush green foliage
• Attracts pollinators

Scarlet Crape Myrtle flourishes in full sun and well-drained soil. It is heat- and drought-tolerant once established and hardy in USDA zones 6 through 10. Regular trimming helps maintain its shape and encourages abundant blooms, making it a vibrant, low-effort addition to any Texas landscape.

Maintenance

Scarlet Crape Myrtle rewards minimal care with colorful growth. Here’s all it needs to thrive in landscapes across Texas:

• Watering: Water regularly during the first growing season to help roots establish deeply. Once mature, Scarlet Crape Myrtle is highly drought-tolerant and performs well with occasional deep watering during extended dry periods.
• Pruning: Prune in late winter or early spring before new growth begins. Remove any crossing or damaged branches and shape lightly to maintain a balanced framework. Avoid severe “topping” cuts - Scarlet Crape Myrtle naturally forms a well-proportioned canopy. Light trimming after the first bloom flush can encourage additional flowering through summer.
• Fertilizing: Apply a slow-release, balanced fertilizer in early spring as new growth appears. A light midsummer feeding can enhance vigor and promote extended blooming. Avoid over-fertilization, as excess nutrients can cause lush foliage at the expense of flowers.
• Mulching: Add a 2-3 inch layer of mulch around the root zone each spring to conserve moisture, moderate soil temperature, and suppress weeds. Keep mulch several inches away from the trunk to prevent rot and pests. Refresh annually for neatness and consistent protection.
• Winter care: Scarlet Crape Myrtle is hardy and dependable through Southern winters. In cooler climates, apply a layer of mulch around the base in late fall to insulate roots from frost. Any light winter dieback will quickly regrow once temperatures rise.

Common Issues and How to Take Care of Them

Scarlet Crape Myrtle is bred for superior disease resistance and low maintenance, but a few minor issues may appear under extreme conditions:

• Powdery Mildew: Appears as a white film on leaves during high humidity. Improve air circulation and apply a fungicide early in the season if needed.
• Aphids: Small green or black insects that feed on new growth. Rinse with a firm spray of water or use insecticidal soap to remove them.
• Sooty Mold: A harmless black coating caused by aphid residue. Manage aphids to prevent buildup, and wipe leaves clean if desired.
• Crape Myrtle Bark Scale: White, cottony patches on bark or stems. Treat with horticultural oil in late winter or early spring before new growth starts.
• Leaf Spot: Brown specks on foliage appearing late in the season. Rake and remove fallen leaves to reduce reinfection the following year.
• Root Rot: Caused by overly wet soil or poor drainage. Plant in a well-drained location and avoid standing water around the roots.
