Do Stump Killers Kill the Entire Root System?

What Happens to Roots After Stump Treatment?

Most stump-killer herbicides (triclopyr, glyphosate, picloram) translocate down into the root system, killing the majority of roots. However:

• Large, distant roots may survive and occasionally sprout.
• If sprouts appear, treat the foliage with glyphosate (Roundup).
• This is uncommon; usually one treatment suffices.

No need to dig roots—they'll decay naturally over time.
