Hi C7, so why not empty entire contents of said Dyson into your bean trench? I'm sure household dust will rot down just as well as everything else that has been suggested.
I hear that fleece (from sheep, not the modern fabric) is good as it absorbs alot of water as well as being a good nitrogen source.
With regards to the newspaper in the bean trench- Do people scrunch it up or leave it at bottom of trench as thick wedge. I put some in my bean trench today and was not sure what to do.
