Honey fungus
Posted: November 22nd, 2022, 5:57 pm
Years ago, perhaps twenty or more, the PO had a large ash tree cut down, but foolishly left the stump. Unfortunately I did not give thought to it.
Last year, a clerodendron maybe 30' distant suddenly died, then another, and then a rosa gallica sp, then this year another rose and a large shrubby lilac at 60' or more, and finally fttb, a large wedding cake tree another 100' on.
Four years ago I had the ash stump dug out, perhaps it was too late , or perhaps honey fungus has come into the garden from spores, it does not only travel underground.
Anyway, until the wedding cake I had no clear evidence that it was honey fungus, although roses and lilac are amongst the known susceptible species. The wedding cake however, which went from healthy to rotting and falling over in 6 months, had the white mycellium beneath the bark. I spent part of this afternoon beginning to dig it out.
Going back 20 years the chemical remedy for honey fungus, or supposed remedy, was Armillatox. One result of the EU's interference was that like many useful garden chemicals such as tar oil winter wash, it was removed as a fungicide in 2003 and the Co that made it was wound up in 2016. So now there appears to be no treatment at all.
Unless you know of anything?
We have many large trees and shrubs in our half acre, including a Kiftsgate 60' high in a large sycamore, both of which are vulnerable.
I hate the thought that one by one they may all die.
