Help! My yard is being invaded by crape myrtle suckers. We removed a tree and thought we had gotten all the roots....not...Round Up isn't working. Suggestions please? I can't rototill because of underground drainage pipes and sprinklers.

Be glad you can't rototill, that would make the situation worse. You'd just be making and spreading more root cuttings.

There is no instant solution here. Roundup, applied correctly, should eventually work. Mowing will eventually work, and weeding your flower beds will also eventually work.

Nope, just took the entire stump out and any large roots. It wasn't a very large stump but I guess all the little roots left behind wanna grow up now. I never had this problem with any other tree but it seems that Crape Myrtle has the Terminator in his genes. Keeps getting up.

I feel your pain, I still have this problem after five years. I was told the sprouts will continue until all of the stored nourishment in the roots has been depleted. I've used stump-killer, RoundUp, had the stumps removed, dug up the roots, etc. They still come back. However, they do seem to be slowing down a bit.

The plan was to replace the area with different shrubs now I'm wondering if I should just leave it bare and cover with a thick layer of bark thereby depriving of any sun for a year. Thoughts, anyone? Or I could pour a cement patio there?

I had an area under a line of six crape myrtles where I planted shrubs and ground cover. Every time I dug a hole, I cut a crape myrtle root and most every root later sprouted a new crape myrtle.

Roundup is your friend.

Try the Roundup blackberry killer. It's stronger. ll the Roundup varieties take a couple of weeks to work.

Try brush killer--find it at tractor supply or other farm oriented supply stores. I would think it'd work on woody plants & kill the root.

Crape myrtle is fully capable of pushing up through mulch.

You'll have to deal with sprouts whether you put down mulch or not.
