4. Bonide


Ready to Use Stump-Out, Easy Chemical Stump Remover for Old Tree Stumps 1 lb., Bonide BND272

Bonide #ad - 1-pound. A while after, you may treat with Stump-Out. No digging or chopping. Fill these holes with water and let it sit for 4-6 weeks. Easy, chemical way to remove stumps. Ready to use - our product is conveniently ready to use when it arrives.

Chemical removal - unlike most other stump removers, Bonide Stump-Out Granules are made from sodium metabisulfite instead of potassium nitrate. Safe to use. Simply apply the non explosive dry granular chemical to the stump as directed. Stump is ready for removal by fire or natural means. Drill 4 holes into the stump and pour Stump Out into each hole. Otherwise, when kerosene or fuel oil is poured onto the stump while it is ignited, the stump can burn down to the roots. No chopping or digging - there is no need to worry about chopping or digging up your tree stumps because this chemical remover will help to accelerate the decomposition of tree stumps.

Use stump & vine killer right after a tree is cut down so it does not re-sprout. Natural or burn - these granules can be used alone on your stumps to accelerate the natural decomposition of the tree. Old stumps - this stump killer is only going to work on tree stumps that have seasoned for 12-18 months prior to treatment.
