Roundup is a selective herbicide and doesn't kill everything. Try a

Actually, it's the other way 'round -- glyphosate (Roundup, et al.) is
a non-selective, systemic herbicide whereas 2,4-D is a broadleaf-
specific selective herbicide.

Negative! Roundup is selective! Read the label and there are dozens
of plants that roundup has little-to-no effect on. I can verify that
by years of experience.

2,4-D is a broadleaf herbicide, but works very well on most woody
plants, especially if they are cut back and the herbicide is applied
full strength to the cambium layer of the plant. This takes the
herbicide directly to the root. It's the best product I've found to
prevent shoots from forming on cut stumps.
