Planting a lagerstroemia
Lagerstroemia can be found either in shrub form, part-stem and full-stem versions. A full-stem version looks like a little tree, with leafage atop a little trunk.
It is preferable to plant it in fall in order to support root development, however you can also plant it until spring, but only on non-freezing days.
In colder areas, planting in spring is best, whereas in other areas fall is fine, after leaves have fallen off.
- Choose a place that is sheltered and more than anything bathed in sun.
- Growth is relatively slow.
- Refer to our guidelines on planting shrubs.
Growing Lagerstroemia in a pot is perfectly possible, especially where winters are harsh, so that you can bring them in for protection in winter.
Pruning and caring for Lagerstroemia
Best performed at the end of winter, preferably during the month of March, either a bit earlier or a bit later depending on the climate (after the deeper frost spells of course).
- Cut the previous year’s branches short to increase the following year’s blooming.
- Remove branches that cross over each other, keeping those facing outwards and removing those pointing back into the shrub.
Prune branches that have grown in the previous year, leaving only an inch (a couple centimeters) or so, checking that you’re leaving an eye facing outwards from the shrub.
- This helps keep a nice silhouette.

In fall, this deciduous tree unveils surprising red, yellow and orange leafage.
In winter, once leaves are on the ground, the trunk appears with beautiful blue-gray-veined patches, much like that of a plane tree.
- Lather the ground with mulch to protect its roots when winters are cold.
- Grow it in a pot and bring it inside away from the cold if temperatures drop below 23°F (-10°C).
