Index of Subjects well I can't get to mow it, it is growing up through a jumble of dumped concrete. I mow where I can get to flat and stopped digging it as I realised that was fruitless, but this spring I did try pouring acid I purchased from a fish plant down into the stalks but it didn't bat an eye. It has travelled across our yard and now is in the ditch across the road and I do worry about that blocking up the culverts as we can get a lot of water coming through there in a tropical storm. As I said birds love it.
