I know, a very exciting photo, of dirt! This is a nationally-available brand of potting soil with fertilizer and I have finally gotten fed up with it. I am now starting to make my own. Why? Mushrooms. Huh? I have been using this and similar soils for outdoor container plants and house plants. Lately, my house plants have been sprouting various fungi! Which I think is not so good for indoor air quality, especially for those with allergies. Why is this happening?
Well, turn over the bag and read the ingredients. Many of these potting mixes list "forestry by products" " forestry products" or "wood chips." You can even see some in the photo. Wood chips take awhile to decompose and often sprout mushrooms and fungi in order to break down. They provide zip in regard to plant nutrients, except, perhaps, over the very long haul. They are there so the forestry industry can get rid of excess, undesirable wood waste.
Another reason to dislike these products is the harsh, chemical salt fertilizers they contain. These are like feeding your kids on white sugar, not healthy at all.
I am now making my own potting soil, a mix of worm compost (other well-aged compost will do), peat or coir fibers and perlite. I think my house plants and I will be the better for it!
Happy gardening!

In some regions, 'spent' mushroom soil (from commercial growers) is resold as 'potting soil.' A scientist friend of mine ferreted out that information and stopped buying it -- by truckloads -- to fill her raised beds.
You are so right in that you gotta read, you gotta ask!
