Question: We have several large tree stumps in our yard that cause a constant rise of unsightly toadstools. What can we do to stop these? Will we have to remove the trunks? E.F., Ohio.
Answer: The toadstools are a saprophytic fungi that live on the dead remains of other plants, in this case the tree stumps. The quickest way to get rid of the toadstools is to remove the stumps. Any chemicals that would destroy the mycelium of the fungi would also destroy the lawn around the stumps.
