To suggest using Japanese knotweed for bee hotels is very risky and ill advised. Cutting knotweed canes in the summer while they're still growing is likely to lead to new infestations, if the canes are not handled carefully and are not allowed to become completely dry. Knotweed can be spread from a piece the size of a little finger nail. So PLEASE DON'T try this at home. Furthermore, I would say knotweed canes, when dead in the winter, are far too brittle to be useful. Far better to find a patch of invasive bamboo that someone has planted as a screen, and harvest that. Please Gardeners' World, think, before offering such irresponsible advice.
