The bagged soil that I use as part of my mix is cheap and local, and it comes with a fair amount of leaf litter mixed in (which I filter out before use). Used alone without that extra step it would be unsatisfactory for succulents. But it has the advantage of being cheap and available and incredibly consistent from one batch to the next. And I can compensate for its shortcomings by mixing in an equal amount of cocofiber and twice as much pumice.
