I hate to see anything go to waste, so cut off the leafy top halves with a view to making a temporary shelter for a test rocket stove, but then realised I wasn't going to have enough time before I had to leave. So I've just laid them pretty thickly in a rectangular area to see if they will act like a light-barrier mulch and kill off the grass and weeds ready to plant in spring. I'm pretty sure by the time I get back there (hopefully next Feb.) the leaves will have shriveled and I don't have much hope of it having killed off any weeds, but . . . I am now wondering if I could make mats with it, to use in a construction project ( too long too explain how here). To do this the reeds would need to be split, like bamboo, so I looked on YT and found
This guy is an artist so I won't be half so fussy about width or anything, but I will definitely be splitting it pretty thin, if it's possible! I'll let you know how I get on in February.
This is an interesting idea too, if the stuff has regrown in three months, I will try this on the new growth
