In warm climates the Crepe Myrtle can be kept outside all year through. In temperate climates it is better to transfer the tree to a cool but frost-free place.

Use a liquid fertilizer every two weeks during the growing season. You can also apply a solid organic fertilizer.

Pruning and wiring

Prune the tree at the end of the summer season. This will encourage bud production for the following year. Wiring is possible but precautions should be taken not to damage the beautiful bark of the Crepe Myrtle. Wrap Paper or tape around the wire before winding it around the branches and remove the wire in time. Whenever possible, use guy-wires instead. Continue reading about pruning Bonsai trees.


Repot the Crepe Myrtle every two or three years. Use a soil mix containing two-fifths organic ingredients. You can also add some organic fertilizer to the soil to promote healthy growth. Continue reading about repotting Bonsai trees.


The Crepe Myrtle can be propagated from seeds and cuttings.

Pests and diseases

Sometimes the Crepe Myrtle is bothered by aphids. Use a specific insecticide or wash the insects off with a strong water jet. Mildew is a more serious problem which occurs quite often. Spray your Crepe Myrtle with a specific fungicide in that case. For more detailed information on these techniques, check out our Bonsai tree care section.
