How to grow and care for Ebony Flame crape myrtle

Like any other ornamental plant, this crape myrtle variety requires you to follow the proper planting and maintenance techniques to thrive. 

To ensure proper care and maintenance for Lagerstroemia Ebony Flame, you need to factor in the following aspects:

  • The spacing when planting
  • Amount of light exposure
  • Soil conditions, soil type, and soil Ph
  • Moisture requirements
  • USDA plant hardiness zones
  • Pruning requirements

Spacing when planting

To form a perfect hedge or screen using Ebony Flame crape myrtle, space each plant 5-6 feet apart. However, if you prefer gaps between the trees, a wider spacing of 10 feet or more between each plant is preferable.


Ebony Flame crape myrtle prefers full, uninterrupted sunlight exposure. However, it can tolerate partial shade if it gets at least 6 hours of direct sunlight per day.

Soil type and pH

Lagerstroemia Ebony Flame can survive in various soil types, including chalk soil, loam soil, and sandy soil. It can only tolerate a narrower pH range than most other types of crape myrtle. Ebony Flame crape myrtle will survive in mildly acidic and neutral soil with a pH of 5.0-6.6, but will struggle in alkaline soil with a pH of 7.5 or higher.


Lagerstroemia Ebony flame can withstand moderate drought conditions and only needs to be watered once weekly in such conditions. You don’t have to irrigate this crape myrtle variety during rainy seasons. It can regulate its intake if it grows in well-draining soil.

However, you need to regularly water young ebony flame crape myrtles to facilitate deeper root establishment.

Note:  consider applying organic mulch about 2-3 inches deep to boost moisture retention in Lagerstroemia Ebony Flame.

USDA hardiness zones

Ebony Flame crape myrtle is well adapted to the following USDA plant hardiness zones: 7a, 7b, 8a, 8b, 9a, 9b, 10a, and 10b. You’ll find the tree thriving in coastal areas such as Jersey to high humidity areas such as Miami and Florida.


The best time to prune Ebony Flame crape myrtle is in late winter or at the start of spring when the plant is ending the winter dormancy period. Pruning at this time triggers the growth of new wood in the spring, from which blooms develop in the summer. Avoid pruning in early or mid-winter, as the new shoots that sprout from the cut branches can’t withstand the cold weather.

Note: It’s also advisable to lightly prune Lagerstroemia Ebony Flame sporadically during the year to get rid of dead and diseased twigs.
