[MENTION=362]buddyo[/MENTION] I have seen those black dots a lot on the vinyl siding of houses we powerwash I believe it comes from specific trees and it definitely doesn’t come off with even close to 3000 psi it would be a real labor intensive deal to get them off
Its artillery fungus. It eats decaying wood like mulch and shotguns its spores off like a shotgun. Very little to do with trees unless they are decomposing
