2021 - What I did today

It's connected with a question that Veggie asked, that if she put potatoes down on a bit of soil 4 inches deep, then covered them with cardboard would she get a crop, so I am going to try growing potatoes in containers, using cardboard/paper, the same soaked in comfrey tea, another mixed with seaweed and one in soil, no doubt someone can direct you to that thread, but not me, I haven't a clue how to find it, other than going through every thread
