I use bags of "top soil" in a potting mix for larger containers and older plants. The product is so variable that I won't buy it without seeing it first.
There must be no standards. I'm just looking for good quality "dirt." The organic matter, I'd like to add that myself so that I know what it is.
It goes through a 1/4" screen and I can use the wood chunks, if they are in there, as mulch in the yard. I add peat moss, compost and perlite. An organic fertilizer can go into the mix either then or later if the plants look deficient.
I have to say that it's only been the last few years that I've grown tomatoes in this mix. This year I've added peppers and eggplants. They all look good so far. Beginning about 7 or 8 years ago, I began with perennials like rosemary and others. They did good so I was willing to try it with other things.
I let the information from The National Sustainable Agriculture Information Service (ATTRA) be my guide.
Their lists of recipes are provided from diverse sources and you see a great variety of ideas. Probably not all of them are suitable for local, available materials or every plant but they can give you an idea that it may be okay to experiment a little.
