What is a good easy cheap soil mix for growing outdoors?

Getting late in the season and I really need to get my babies in the ground Please help with something I could easily find at walmart maybe

Get some peat moss, add in some worm castings qbout 20%, and then add some bat guano if you can get it and youll be good. Nice and fertile mix and its organic

miracle grow is cheap and works just fine.

Be careful of MG soil unless you plan on having them in the ground for more than 6 months. Time release ferts. Stay away from the Kellogg soil they carry, imho. Had nothing but grief while using it.
