Crepe Myrtles are the cockroaches of the tree world.

Am I pretty much screwed here?

We had an ugly crepe myrtle in our front flower bed, I cut it down, drilled holes in the stump, filled the holes with Roundup every few days and gave it about 4 months. Yanked the stump out with a truck, passed a stump grinder on the area, and thought all was good. Repaired the area and replanted other things there.

Fast forward about 6 months and I'm pulling crepe myrtle sprouts every week. Am I pretty much doomed to deal with this forever or is there something I can do to end this outside of going nuclear on the whole area?

I like crepe myrtles and magnolias. I'm a masochist, though.

Pulling them or putting round up on them wont get them to go away. You basically have to suffocate them over time with a stump/root killer applied directly to a fresh wound on the shoot ups. When you mow apply a product like below to the fresh wounds. I am going on year two of painting mine every couple months and its getting better and better. Unfortunately there is no instant fix that I know of.

I don't mind them as well, the crepe myrtles in the backyard are staying and replaced this one with a magnolia. The previous owners had topcut it and it looked terrible.

Pulling them up worked for me but I did it with my truck and connected to the tree, didn't cut them down first. That pulled up all the roots basically. Then we had one or two places that popped up. Don't recall what I hit them with through, it was a decade ago or better.

I meant pulling up the shooters, not the root. He mentioned he already grinded the stumps which is the same thing I did. Pretty much impossible to pull up the tree and trunk with a truck if they are older, larger, mature crepe myrtles unfortunately.

Mix a cup of straight roundup and remedy together 50/50. Use a latex glove and dip your fingers in the mixture then paint on the sprouts. Will smoke those little spawns of satan after 2-3 applications. Glove method will prevent from killing too much grass.

I made Mistake of digging up a couple with excavator and after fighting trying to pull or dig up landed on receptor above and smoked em.

I've got several small crepe myrtle stumps next to an elm tree.... want to keep the elm but kill the crepe. I guess this method would only affect the crepe root system?
