I apologize for this delayed reply to your gardening question and hope it is still helpful to you.
Go ahead and come away and he shoots coming from the base of the plant now, making sure to cut us close to the trunk as you can so as not to leave a stub. This will not affect the plants blooming this year and it's better to go ahead and get rid of them now. Crape myrtles bloomed for about three months and then play out and ceased to bloom for the rest of the year in most cases.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
