Introduction to Crape Myrtles
Crape myrtles (Lagerstroemia species) are among the most beloved flowering trees in warm climates, offering spectacular summer blooms when few other trees flower. With their clouds of colorful flowers, attractive exfoliating bark, brilliant fall foliage, and sculptural winter silhouettes, crape myrtles provide year-round interest.
Native to Asia and Australia, these versatile plants range from compact shrubs to tall trees, making them suitable for any landscape. Often called the "lilac of the South," crape myrtles thrive in hot, sunny locations where they bloom prolifically from midsummer through fall.

- Long bloom season: July through September (or first frost)
- Four-season interest: Flowers, fall color, bark, winter form
- Heat lovers: Thrive where summers are hot
- Drought tolerant: Once established
- Size variety: From 2-foot shrubs to 30-foot trees
- Color range: White, pink, red, lavender, purple
- Attractive bark: Beautiful exfoliating trunks

What You'll Need
Essential Supplies
| Item | Purpose |
|---|---|
| Crape myrtle plant | Container or B&B |
| Mulch | Root protection |
| Watering equipment | Establishment irrigation |
| Loppers/hand pruners | Maintenance |
Site Selection
Choose a location with:
- Sun: Full sun (minimum 6 hours)
- Soil: Any well-drained soil
- Space: Allow for mature size
- Air circulation: Reduces disease
Important: Crape myrtles bloom on new growth—the more sun, the more flowers!
Step-by-Step Planting Guide
Step 1: Timing
Plant crape myrtles in spring (after frost) through early fall. Avoid late fall planting in colder zones.
Step 2: Site Preparation
- Choose the sunniest spot available
- Test drainage—avoid soggy areas
- No need to amend most soils
- Mark the mature width for spacing
Step 3: Planting
- Dig hole 2× wider than root ball
- Dig only as deep as root ball
- Set plant at or slightly above grade
- Backfill with native soil
- Water deeply to settle soil
- Apply 3-5 inches of mulch
Step 4: Aftercare
- Water regularly for first season
- Reduce watering once established
- Fertilize lightly in spring
Basic Care Guide
Watering
| Stage | Frequency | Notes |
|---|---|---|
| First year | Weekly deep watering | Critical for roots |
| Established | During drought only | Very drought tolerant |
| Extended heat | Supplemental watering | Improves bloom |
Fertilizing
| When | What | Notes |
|---|---|---|
| Early spring | Balanced slow-release | Light application |
| Summer | Usually unnecessary | Excess promotes foliage over flowers |
| Avoid | High nitrogen | Creates leggy growth |
Pruning: Avoiding "Crape Murder"
The wrong way (Crape Murder):
- Topping all branches to stubs
- Creates ugly knobs
- Weakens tree structure
- Reduces flowering
- Invites disease
The right way:
- Remove crossing branches
- Thin interior for air circulation
- Remove suckers from base
- Cut to natural branching points
- Maintain natural form
When to prune: Late winter, before new growth
What to Prune
| Remove | Keep |
|---|---|
| Dead/damaged wood | Natural tree shape |
| Crossing branches | 3-7 main trunks |
| Suckers at base | Well-spaced branches |
| Low branches (if desired) | Flower-producing tips |
| Spent flower clusters (optional) | Structure |
Common Problems and Solutions
Diseases
| Disease | Symptoms | Solution |
|---|---|---|
| Powdery mildew | White powder on leaves | Plant resistant varieties, improve airflow |
| Cercospora leaf spot | Dark spots, leaf drop | Fungicide if severe, sanitation |
| Sooty mold | Black coating | Control aphids (the cause) |
Pests
| Pest | Symptoms | Solution |
|---|---|---|
| Aphids | Sticky leaves, honeydew | Insecticidal soap, beneficial insects |
| Japanese beetles | Skeletonized leaves | Hand pick, traps |
| Crape myrtle bark scale | White waxy coating | Horticultural oil, systemic insecticide |
Quick Reference Growing Guide
| Factor | Requirement |
|---|---|
| Sun | Full sun (6+ hours) |
| Soil | Any well-drained |
| Water | Drought tolerant (established) |
| Hardiness | Zones 6-10 (varies by variety) |

Troubleshooting Guide
| Problem | Cause | Solution |
|---|---|---|
| No flowers | Too much shade or nitrogen | Increase sun, reduce fertilizer |
| Sparse bloom | Over-pruning | Let tree grow naturally |
| White powder on leaves | Powdery mildew | Resistant varieties, airflow |
| Black coating on leaves | Sooty mold from aphids | Control aphids |
| Yellow leaves | Normal fall color | No action needed |

Your First Steps
- Choose the right size: Match variety to space
- Pick a sunny spot: More sun = more flowers
