commercial grade fertilizer the 13/17 refers to the % amount of phosphorus, nitrogen, potassium in the mix. its what damn near everyone uses north to south. If you knew your PH level you could add or detract what was needed to make the soil more or less acidic as needed, between 4-7 is the basic guideline on soil ph.
edit- had a truck. But anyway this will explain ph better than i can. if you dont wanna screw w/ it just sprinkle a teaspoon of 3-13 around each plant and abit less 3-17.
i paid i think 10$ for a 50# bag and spead it over the yard and garden then kept some in reserve for spot fertilization. This is how i learned to do it from dad & grandpa.
