Physically removing a tree stump requires more tools than most home gardeners have at their disposal. And hiring a tree removal service can be expensive. Many homeowners choose to dissolve tree stumps on their property with chemicals. But, despite the claims of many commercial products, this process does not happen overnight. Any number of chemicals can be used to dissolve a tree stump, but they merely accelerate the decomposition process and it can take years to completely dissolve a tree stump.
Use an axe or a chainsaw to cut the stump as close to ground level as possible.
Drill several holes into the main stump that are at least 1 inch in diameter. The more holes in the stump and the deeper they go, the more quickly the tree stump will dissolve.
Fill each of the holes with an accelerant. Rock salt,, commercial stump killers, high-nitrogen fertilizer, potassium nitrate (saltpeter), sulfuric acid, nitric acid, sugar and stump-killer are all acceptable accelerants that speed the decomposition process to varying degrees.
Pour boiling water into the holes repeatedly until all of the chemical has dissolved and absorbed into the stump.
Repeat steps three and four every six weeks until the stump is decomposed.
