I haven’t had too much trouble finding locally-produced potting soils at the garden store, but I’m unsure of how to determine quality / value compared to more well-known brands.

A couple years ago I bought a locally-made bag and it had literal plastic garbage mixed in, like someone scooped dirt out of a field and didn’t sift it at all. (Admittedly probably only a reflection on that particular product.)

I’ve also tried PROMIX and it was okay, though a bit expensive for the size of the bags I can find. (It also looks like that one is produced in Quebec but for an American company called Premier Tech.)

Has anyone used any Canadian-made potting soils in their garden? (e.g. For raised planters or pots, etc.)
