View Full Version : Artillery Fungus & Mulch

I have some new clients that seem to have artillery fungus (black tar like specks) on their house and cars from a previous mulch job a couple years ago. They have tried powerwashing etc... and no luck.

Has anyone ever dealt with this? My main question is if I pull the infested mulch out and replace it with new is the fungus going to come back because it remains in the ground or just in the mulch itself?

It's also my understanding that there aren't any chemicals that are labelled to kill off this fungus.

Any help would be greatly appreciated.

Rodney,
I believe all hardwood and root type mulches including dyed mulches and ICBIN produce artillery fungus. Around here only cedar is available that won't have this problem. I would suppose that cypress and pine mulches would also NOT produce this fungus.
