I’ve got a cherry tree of some variety (at least, I think that’s what it is). Last winter, some black fungus clusters started forming on some of the branches. I figured I should snip them all off the tree and managed to get quite a few of them before spring, hoping that the fungus wouldn’t spread.

Well, it’s back this winter and it’s on some branches that I can’t reach, as well as also being present on a knot where the previous owner had removed a low branch.

Is there some kind of treatment for my poor tree aside from cutting out all the fungus?


  • can you add a photo or two of this fungus please? – Bamboo Mar 16 '19 at 17:45
  • is it a burl, or chaga? – black thumb Mar 16 '19 at 20:17
  • I do not understand either of those words, so I’ll have to get back to you on that. – Ian MacDonald Mar 16 '19 at 22:05
  • That’s a yes to chaga. – Ian MacDonald Mar 16 '19 at 22:08
