After my order for was not fulfilled by Penjing Iron Works, I started searching for alternatives but most soil are far too expensive for me.
I don't have much experience with bonsai & have researched for hours but nothing seems conclusive. I've read that Diatomaceous Earth (NAPA oil absorbent) is ok for use as bonsai soil. Should it be mixed with bark or something else? I have all tropicals & one that needs repotting ASAP. So does anyone have experience with this?
