Get rid of crape myrtle

About 5 or 6 years ago I removed a crape myrtle so I could expand my rose garden.  I got down quite a way to remove stump and roots.  I put weed cloth down and covered it with bark.  Ever since I have been fighting it.  It will find any hole or crack in the weed cloth.  At first I put round up on it, but that did bad things to the roses near by.  Now I try not to use round up at all, ( I try not to use any of those bad chemicals any more) it didn't work anyway, oh the part I put the round up on would die, but it would just pop up somewhere else.  At this point I just pull what I can see out so it doesn't get big and take over.  I need to put more wood chips on, but even that never stopped it.  Any suggestions are welcome, since weeds rule my life, yes I consider it a weed at this point. I would love to have one less to deal with.  Thanks

Did you dig out the stump?  If not, you've got to start there.

And then working from the stump outward, you need to expose the major roots that still exist and pull them up.  Yes, it's a tremendous amount of work.  If you can hook a chain to them, you can pull them out with a tractor/ATV/truck/whatever.  Water the ground well a few days before you try this, as they are tough and difficult to remove if the ground isn's soft.

Crepe Myrtle and Whisteria are amazing plants that people commonly plant for their floral display, in that their roots stay alive for years and years after the above-ground plant has been removed.  I've had whisteria pop back up to the surface 10+ years after I cut it down.

Ugh, they are awful to get out. I had some that were totally feral, sending out suckers. I - no joke- used a long blade on a sawzall in a circle on the outer edge of the clump. Deep as it would go. Then took a San Jose Bar and leveraged out the stumps. And they still came back. Jeff Lawton sayd it takes two years to kill a re-emerging plants, but I have dealt with wisteria and crap myrtle enough that I think that totally depends on stored energy in the root. I'm on year four of the crap myrtle battle. I've tried 30% acetic acid, repeated San Jose bar removal. Still here. My next attempt is going to be a big pile of fish parts on each clump and try to burn them with nitrogen.

I've tried pulling clumps out with a chain on the tractor, but one clump that breaks and releases the tension quickly fixed that idea...

"Thanks for the extra nitrogen!  Bwww, haaa, haaa . . . someday we'll take over the whole world!", said the hungry Crape Myrtle.
