Choosing the Right Crape Myrtle Variety
Before diving into maintenance, selecting the right crape myrtle variety is key to long-term success. In Southeastern NC, these varieties thrive:
- Pink Blooms: ‘Pink Velour,’ ‘Sioux,’ ‘Tuscarora’

Each variety offers unique benefits. ‘Natchez’ provides a classic look with white blooms and elegant peeling bark, while ‘Dynamite’ creates a bold red display. Choosing the right crape myrtle variety ensures it complements your overall landscape maintenance and design beautifully.
Essential Crape Myrtle Care Tips
1. Watering for Strong Growth
Crape myrtles are drought-tolerant once established, but proper watering is crucial, especially for young trees.
- Newly planted crape myrtles need deep watering 2–3 times per week for the first two months.
- Established trees require water during dry spells—soak the soil when the top 2–3 inches are dry.
- Avoid overhead watering to prevent fungal diseases. Focus on the root zone instead.
2. Fertilizing for Healthy Blooms
To encourage lush foliage and vibrant flowers, fertilizing at the right time is essential.
- Apply a slow-release fertilizer in late winter or early spring.
- A second feeding in July boosts mid-season blooms.
- Use a balanced 1-1-1 NPK ratio to promote steady growth without excessive foliage at the expense of flowers.
3. Pest and Disease Prevention
Crape myrtles are hardy, but they can fall victim to pests and diseases. Be proactive to keep them healthy:
- Japanese Beetles: Remove them by hand in the morning or shake branches over a bucket of soapy water.
- Aphids: Spray with a strong water jet or use insecticidal soap.
- Powdery Mildew: Prevent this common issue by ensuring good air circulation and applying fungicides when necessary.
If you’re dealing with pest infestations or disease issues, professional shrub and tree care services can help protect your landscape.
4. General Maintenance
Keeping your crape myrtle healthy involves more than watering and fertilizing.
- Plant in full sun to maximize bloom potential.
- Mulch properly using high-quality mulch installation to retain moisture and suppress weeds.
- Protect the base by creating a tree ring with mulch to prevent lawn mower and weed eater damage.
Additionally, keeping flower beds tidy with regular bed maintenance helps improve the overall health and aesthetics of your landscape.
The Best Way to Prune Crape Myrtles
Pruning plays a major role in crape myrtle care, helping to shape the tree, remove dead or damaged wood, and promote new growth. But improper pruning can do more harm than good.
When to Prune
The best time to prune crape myrtles is mid-February, before new growth emerges. Avoid cutting too late, as it can stress the tree and delay flowering. For a structured approach, consider a winter pruning service to ensure your trees receive expert care.
How to Prune Correctly
When pruning your crape myrtle, focus on enhancing its natural shape rather than controlling its height.
- Remove crossing, rubbing, and dead branches.
- Cut off suckers at the base to maintain a clean appearance.
- Trim frost-damaged wood back to healthy stems.
- Deadhead old flower heads by cutting just above an outward-facing bud.
Proper pruning ensures balanced growth and encourages strong, beautiful blooms.
Avoiding “Crape Murder”
One of the biggest mistakes homeowners make is over-pruning, often referred to as “crape murder.” This happens when branches are cut back to ugly stubs, damaging the tree’s health and appearance.
Why It’s Harmful
Improper pruning can:
- Cause weak, spindly growth that can’t support flowers.
- Reduce bloom production for the next growing season.
- Leave permanent, knobby scars that ruin the tree’s shape.
- Make branches more susceptible to breakage, pests, and diseases.
Instead of topping your tree, use selective pruning to maintain its natural beauty and structure. If you need a smaller tree, choose a compact variety rather than trying to reduce height through excessive cutting.
Conclusion
Crape myrtles add beauty and value to your landscape, but they require proper care and pruning to thrive. By selecting the right variety, following a consistent watering and fertilizing schedule, and avoiding common pruning mistakes, you’ll enjoy healthy, vibrant blooms year after year.
