i have 7 yards that i do in a subdivision and they all buy the scotts fertilizer and have asked me to apply it next season for them. i don't want to loss them and don't want to get fined either. they all want the 4 step appl. for the season. i don't want to get into the fertilizing but if they buy it and i'm there why not? it will only be scotts fert. from home depot or lowes nothing else.
