So while we were weeding and clearing the bare patch where my melons and zukes failed so miserably last year we stumbled upon this gigantic hardwood stump buried about 6 inches deep. The roots are huge and spread at least 8m from the stump. The thing was covered in a strange white mould and was the palace of an enormous ant colony. It’s obvious that my ant baits last summer did have some effect, but they were still survivors in there starting again.
So, for these reasons we decided to remove as much of it as possible, even though we are building raised beds on top of it, and could theoretically have left it there. Bens’ phobia of termites also played into it.
So we can’t afford a professional. Instead we bought a new chain saw chain and Ben hacked away at it. (We know that’s not great for the chainsaw btw). The roots are still there, but are less ant eaten, we’ll remove as much as we can, but I doubt it will be a huge % of what’s there. We had to rip up brickpaving as it was.
So I’m guessing this is the source of the rapid fungus that killed my lovely vine patch. One of the zukes was planted directly over it. My theory is once the roots grew down to the infected stump it spread all over. :(
It’s also definitely the source of the unkillable ants.
Hopefully its removal will be a blessing when we do eventually build our raised boxes there. :)
