Ok, here is my situation. I have an allotment (Which is just a big plot of land), and I was thinking of making part of it a mini bog. I have pleanty of Sphagnium moss peat and some perlite, I have loads of dead sphagnum moss, I know it can come back to life given the right condidions. But what would that be? Should I make the bog raised above ground, or make it at ground level?
