Use of diatomaceous earth in Al's soil mix?
Hello all. While in an auto parts store over the weekend and saw a 25lb bag of oil absorber. Normally I wouldnt have thought of using this in planting continers, but having read several threads on various bonsai websites recently I know that some people use this extensively in their soil mixes.
This particular soil absorber was composed of diatomaceous earth. I've heard that diatomaceous earth products are fairly stable and typically last much longer than cat litter or other non-diatomaceous earth oil absorbing products.
I'm wondering what the group thinks of using diatomaceous earth in container soil mixes?
The reason I ask is that some members cannot find Turface locally. If this diatomaceous earth oil absorber is a good product and won't break down in soil mixes, perhaps it could be a substitute for Turface? Nearly every town or city has an auto parts store.
Any thoughts on this?
