Killing crepe myrtles
We had 2 crepe myrtles cut down and the stumps ground from our flower bed. (Should never have had them ground)

Is there anything I can spray the new sprouts that keep popping up to kill the roots? I dig up about 10 small pieces of root and bark every day attached to the sprouts.

Is there still some kind of base or trunk under ground? If so, I’d try to expose it, wet it and salt it and try to keep it salted. Maybe a heavy layer of table salt first and then rock salt. I really don’t know if that would work or not. But that’s what I’d try.

No, they ground the stump leaving small pieces of stump and roots.

re: Killing crepe myrtles
Commercial herbicide sprayers use various residual herbicides/soil sterilants with their non-selective herbicides mixtures, that would probably work. DuPont Hyvar X is one. It would not allow anything to grow for some time, and proximity to desirable plants would also be a concern. Once it’s down, it may take a year for two to wear off. And that’s if you could even find a way to acquire some. It’s specifically labeled -not for use around homes. I had gotten my hands on some Hyvar X powder years ago. It works. I see that Bayer bought it out in 2014 and has it in Hyvar XL, liquid form. The one I had is linked below. But both show out of stock there. This would be an extreme measure with caution advised.

Hyvar X

Edit- looks like the liquid is available. Not sure if the statement that license required is for the states listed or is all inclusive. $145/gallon. Probably last you the rest of your life though, as it’s not something to sling around indiscriminately

Hyvar XL

Phenoxy herbicides. But needs to be applied when it’s less than 80 out, so usually not effective in summer. Also, they have shallow roots so it’s not too crazy of an idea to remove the roots.
