Ihave a bad dose of honey fungus all around an old tree stump so far nothing seems to kill it the toadstools are in a large solid mass, would burning them control the spread?, we are really running out of ideas,the stump is about four foot high and three foot circumference, we have been using it as a bird table since it was cut down two years ago it was a twenty foot plus tree, hope someone can come up with a solution, apart from hiring a tree specialist to remove it thanks.
