Hi All Just wondering if any of you use charcoal from burnt greens like arrowroot in your garden systems, the course I did on the weekend that lightly covered this process and use, I would like more information if you have any. This is not about using coal and ash from dry wood fires, this process uses uses a few different plants like arrowroot. We also covered making potash from burnt orange skins, which is a great idea, you make a kabab from a green stick and half orange skins, then charcoal them and just lightly tap the kabab around your cirtus adding small amounts of potash. Beats buying it. You only need small amounts of this potash too.
