Q: I want to kill a mimosa stump. Every time I cut it down sprouts reappear.
A: Some trees and vines are impossible to kill just by cutting them down. Their roots and stump are primed to sprout after you cut off the main part of the plant.
To prevent re-sprouting, use glyphosate (Roundup, etc) or triclopyr (Brush-B-Gon, etc). Immediately after cutting a sprout, use a disposable paint brush to paint undiluted herbicide on the cut stump.
For large stumps, chop around the edge of the stump with a hatchet and paint the chemical there as well.
