Question

We have lots of crepe myrtles on our property..As they are getting older I don’t like the space between the 2 trees..They were just put in the ground by my father in law..No kind of order..Is there any plants I can plant in between them..We also have some japanese yucca..Can they be planted in between trees or will they out do the other..Don’t want to lose my crepe myrtles.. I was thinking of some sort of bulbs..Definitely want a perennial so it will come back each year.. we have at least crepe myrtles,maybe more..Thank you

Answer 1

Meant to say we have at least 50 crepe myrtle trees..All planted by my father in law when they lived here...thank you
