Crepe myrtle does something that few other blossoming trees do – they bloom in high summer. It’s worth learning how to grow crepe myrtle in your garden for their fabulous crepe-like flower heads in shades of pink, red, mauve, purple and white. They bloom through January and February and they are native to southern and eastern Asia, but they grow well in most parts of Australia.

Crepe myrtles make excellent summer shade trees yet they have lots to offer through the other seasons of the year, with brilliant foliage colour in autumn and attractive smooth bark when they’re leafless in winter, which creates an elegant silhouette in the garden landscape.

Where do crepe myrtles grow best?

Crepe myrtles make ideal feature trees for home gardens, because they’re compact in size, and respond well to pruning. All crepe myrtles need to be grown in an open sunny position, and young trees should be watered generously through summer. Because of their compact size, they make very good street trees.

How to prune crepe myrtle

Crepe myrtles respond well to pruning, which is best done in mid-winter, when trees are bare of leaves. To keep them compact, trim back branches by about 30cm all over.

If you wish, you can cut them back much harder than this – they’ll send out long arching branches from the site of the cut when spring arrives. However, if you’re not into pruning, and you have enough space for them to develop their naturally appealing shape, just leave them alone – they’ll flower well in any case.
