Removing a tree stump using mulch (alongside dirt or grass) is both convenient and easy. Next, add mulch and dirt to the stump and the immediate area surrounding it. Choosing the best type of mulch for this process is crucial. Make sure you slap as much mulch and dirt as possible on the entire stump to create the best conditions for decay. By this time, the stump should hopefully topple over without much effort, or at least be loose enough to uproot.
