- Watering
Although crape myrtles are fairly drought tolerant, they perform best in moist soil. Make sure newly transplanted plants are watered often - Fertilizing
Crape myrtles respond to fertilization. Since many types are fairly fast growers and they produce copious blooms they benefit from extra nutrition - Mulching
A 2 to 3 inch layer of some attractive organic material spread on the soil over the crape myrtle root system has many benefits - Pruning/Grooming
Crape myrtles may be pruned for health or control purposes. All types of this plant may need to have diseased or damaged stems cut out from time to time. - Winter Protection
In the northern reaches of its range, crape myrtle will benefit from some winter protection. Water the tree generously before the ground freezes and increase the mulch layer to 4 inches to insulate the ground somewhat from fluctuating temperatures over the winter.
