Answer: Hi Warren,  I wouldn’t cut it. Firstly, roots almost never affect water supply pipes. They sometimes grow into drainage pipes that are incorrectly installed or are made of terracotta. If you cut that root, then dozens of crepe myrtle suckers will emerge all over the lawn for the next 50 years or so. Bad idea Warren…Don
