When to Plant Crape Myrtle in Arizona

Growing Crape Myrtle in Arizona: 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 Arizona falls between February 1, 2027 (Zone 10a) and May 2, 2027 (Zone 5b); early fall works too, once summer heat breaks.

Because Arizona stretches across 10 USDA hardiness zones (5b, 6a, 6b, 7a, 7b, 8a, 8b, 9a, 9b, 10a), planting windows can shift by as much as six to eight 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. In the arid Southwest, intense sun and low humidity mean irrigation is essential; mulch to prevent rapid soil moisture loss.
