The local nursery sells Soil-Pep and a variety of other compost like the peatmoss and a few other "planting soils", but they claim the Soil-Pep (which is the least expensive by far) lasts longer and is every bit as good as the Scotts, Miracle-Gro, and other well-known makers of compost. Making my own compost is out of the question, BTW.

I would like to know of the experiences others have had, good and bad, using Soil-Pep versus the SPM and other purchases composts.

 

I don't know much about the other fertilizers you talked about, but have had good results with peat moss. Peat moss is very good for improving drainage in clays and loams, but in large quantities lowers the pH, so alkaline soil loving plants beware. Oh, and MiricaleGro®. I used to use it before I went organic. It works well.I don't use it only because I'm "picky" about organic stuff. If you grow organically you will want to find out if those others are all natural, but other than that I'llleave it to other DIY guys who have had more experience with them

 

How much of this are you planning to use? A few pots, a small bed, or hundreds of square feet?
