- Prolific blooms that last for months
- Attractive, peeling bark that adds winter interest

Growing Conditions for Crape Myrtle
To thrive, crape myrtles need:
- Full sun (at least 6 hours a day)
- Well-drained soil
- Moderate watering during their growing season
Once established, these trees are highly drought-tolerant, making them ideal for regions that experience long, dry summers. Be sure to choose a location with ample sunlight for maximum bloom production.
How to Plant and Propagate Crape Myrtles
Planting crape myrtles is a simple process:
- Choose a sunny location.
- Dig a hole twice as wide as the root ball.
- Place the tree or shrub in the hole and backfill with soil.
- Water deeply to help establish the roots.
Propagation can be done through cuttings, seeds, or layering, but cuttings tend to be the easiest and most successful method. Take softwood cuttings in spring, dip them in rooting hormone, and plant them in a mix of soil and sand.
