Burning: This method requires application of chemicals and isn’t the safest method, especially if the stump is close to buildings or other flammable material. A stump will smolder for hours and must be watched until it burns out.
Chemical: This method takes weeks to break down the stump and it must be kept covered so that children and animals do not come in contact with the chemicals. The stump will gradually break down to the point where it can easily be broken apart into small pieces, but typically some portion will remain and require burning. After the stump is gone, traces of toxic chemicals will remain in the surrounding soil.
Decomposition: The rotting method can take a tree stump up to 10 years or longer to fully remove the stump, and during the process it could become a harbor for insects.
