crepe myrtle growing like a bush/

Question

my aunt planted a crepe myrtle. The one we planted has grown up tall; hers on the other hand, has grown like a bush? How did this happen and is there a way to fix this?

Answer 1

Some cultivars are more like a shrub, while others are like a tree. It is preferred to treat them like a tree for a better looking plant,and healthy plant keeping all undergrowth pruned away.

If you cut the tops off each year they will grow into a shrub, but this comes with its downfalls as well. They are susceptible to infections from lack of airflow when they are short.
