What you will see

Rotting roots, white mycelium under the bark, black bootlaces (rhizomorphs) in the soil, sudden death; mushrooms in fall.

    • Choose species that honey fungus rarely attacks (e.g. Vaccinium).
  2. By handA deep barrier (17¾ in) of rubber sheeting in the soil blocks the bootlaces; regular deep cultivation breaks them.
