Oak Root Fungus on Camellias?

I have recently had a number of mature plants in my San Francisco garden killed by Oak Root Fungus (Armillaria mellea), including crabapples, Japanese maples, and perennial Fuchsia arborescens. Located near the infested areas, I have a number of C. japonicas, as well as a 20-year old, very large C. reticulata. Does anyone have any information on whether these plants are resistant or susceptible to the fungus? Any input on the subject, including links to relevant websites, would be very much appreciated.

Well, when you research this topic (Armillaria) what you end up with is that you really cannot count on anything being definitely off the menu. Consider rooting around with a trowel periodically and pulling up the bootlaces. These grow up onto the crown of the plant and kill the top, thereby creating more dead plant matter to digest.

Another thing is that Armillaria need to stay moist, if you are irrigating try experimenting with cutting that off. Up here camellias are actually recommended for their drought tolerance. In a hot region these east Asian monsoon climate shrubs would presumably require some assistance to get through the summer.

" Armillaria mellea " is one of the worst diseases that could have a garden.

Any weak tree, one will see affected. You must withdraw all the remains of the affected trees and burn them.

Also you must withdraw all the roots and burn them. There are approximately forty species of the Genre Armillaria, but A. mellea is the worst.

You garden must avoid the flooded water..
And to begin to give treatments against the Armillaria mellea, of regular form.
Perdon for my evil english.
