When And Where To Plant Crepe Myrtles are easy to plant and grow in full sun and well drained soil. They require moderate moisture, but always water deeply. The best time to plant dormant, balled and burlapped plants is December through March, after the leaves have fallen. Container grown crepe myrtles can be planted year round.
Planting Dig a hole twice as wide and the same depth as the root ball.
