Bonide Stump Out Tree Roots Decomposition Accelerator Granules 1 lb

Chemical Removal-Unlike most other stump removers, Bonide Stump-Out Granules are made from sodium metabisulfite instead of potassium nitrate. Old Stumps-This stump killer is only going to work on tree stumps that have seasoned for 12-18 months prior to treatment. Use Stump & Vine Killer right after a tree is cut down so it does not re-sprout. A while after, you may treat with Stump-Out.
