I am planning to replant my ficus and palm in Napa oil spill cleaner. It is 100% diatomacious earth and I got the tip from some website. I have heard that hobbyists in the UK are using Cat little that is also this same material, although no cat litter like that seems to exist across the sea.
I was just wondering if anyone here uses this as soil? Also should I use it by itself or mix it in with another soil ingredient?
