When to Plant Crape Myrtle in Oklahoma

Growing Crape Myrtle in Oklahoma: Complete Guide

Crape Myrtle (Lagerstroemia indica) is planted as nursery stock — a container-grown or bare-root plant from a garden center, not seed. Depending on your zone, the ideal spring window in Oklahoma falls between March 27, 2027 (Zone 8a) and April 22, 2027 (Zone 6b); early fall works too, once summer heat breaks.

Because Oklahoma stretches across 4 USDA hardiness zones (6b, 7a, 7b, 8a), planting windows can shift by as much as two to four weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

Crape Myrtle requires full sun (6+ hours) and low once established moisture. Great Plains gardens face strong winds and variable moisture — windbreaks and drip irrigation help significantly.
