Potassium nitrate is a fast-acting method to rot tree stumps. Drill holes into the stump and fill them with potassium nitrate, then add water. Over weeks, it accelerates the decomposition process. An alternative is Epsom salt, applied similarly, that speeds up rotting over months. Covering the stump with a tarp after application keeps it moist and promotes faster decay.
