Hardiness Zones

USDA Hardiness Zones indicate the regions where different plants thrive, based on relative low temperatures in winter. Zones 7-10 are ideal for Twilight Crape Myrtles, especially across the Southeast.

Planting

The best time to plant Twilight Crape Myrtle trees is late fall or early spring. Choose a site that receives full sunlight and amend your soil if necessary. Pull any weeds and remove any turfgrass or debris. Dig a hole about three times the width and depth of your root ball. Remove the root ball from the container, and loosen it up with your fingers.

Place the root ball so that its top edge is slightly above the surrounding soil level. Backfill the hole with native soil, gently tamping it down to remove any air pockets. Water the area up to the depth of the root ball.

If you plan to plant a privacy screen, plant the trees 10-12 feet apart.

Growing Conditions

Twilight Crape Myrtles can grow in a range of light and tolerate drought but have some soil preferences.

Sun and shade

Twilight Crape Myrtles thrive in full sunlight—at least six hours of direct, unfiltered sunlight per day. They can grow in partial shade as well, but they will flower less.

Soil

Twilight Crape Myrtle trees thrive in well-drained, acidic soil with a pH level ranging from 5-6.5. Most plants thrive at a pH level of 6.5-7, so you may need to amend your soil. Applying sulfur can make your soil more acidic.

Watering

Twilight Crape Myrtles are drought-tolerant when they are established, but you should water them once a week after they’ve just been planted to help encourage deep, strong roots. After a few months, you can reduce watering to once or twice a month at a depth of six inches.

Fertilizing

Feed your tree with a nitrogen-rich, slow-release fertilizer in the spring as soon as the leaves emerge and then again in early fall. Choose a balanced fertilizer with an NPK value of 10-10-10 or 8-8-8.

Pruning

Twilight Crape Myrtles don’t require pruning, but cutting them back can help create a denser canopy and produce even more deep-purple flowers. The best time for pruning is late winter.
