Cut Stump Cut stump treatment is when an herbicide solution is applied directly to the cut portion of a stump "immediately after cutting down the plant. The herbicide kills the stump and prevents new growth that would normally occur after cutting alone." (Source: Alabama Cooperative Extension)
The herbicide can be applied to the cut portion of a stump with varying tools, brush, squirt sprayer, sponge applicator, etc.
The herbicide used varies on the plant being treated.
