I purchased a 2lb bag of Canada Green Lawn Grass Mixture, I have a lot of bare spots and areas that need grass. I live in East Texas on Cedar Creek lake, the soil in my front lawn in more of a sandy color texture and the back is more dirt, someone told me to use a lime type fertilizer, I think that's what he said, what is your opinion and should I use the same type of fertilizer for the back yard? Any guidance you could give me would be appreciated.
