Lagerstroemia is an amazing shrub or tree that blooms during the entire summer. 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. Pruning and caring 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 years branches short to increase the following years 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 a couple centimeters or so, checking that you’re leaving an eye facing outwards from the shrub.
