Explaining “Root Rot”
It is parasitic on oaks and other plant species, but if these plants are growing in our environment of moist winters and dry summers, this fungus is normally kept in check. However, if summer irrigation is provided, Armillaria can become an aggressive, deadly pathogen. Armillaria is an opportunist that will also attack plants that are under stress either by damage to the roots or because of improper watering.
The fungus can live many years as a saprophyte in soil, on infected stumps, roots, and other organic matter. It breaks down the lignin and cellulose in plant tissue. Natural oak-root infections will not threaten the native oak's life. A few roots may be infected, but the tree can replace them.
