Hi, just moved into a house and the previous owner did not maintain his grass that well. My grass is very thin, grass can be easily ripped up. I went to lowes and was speaking to a guy there who told me to put down scotts thick r lawn which is a seed and fertilizer in one. I put that down a week and a half ago. I should have done my research before asking someone at lowes. I know have dandelions coming up all over my lawn and i read online that i cant put a weed and feed down because i seeded. Is that true, any advice on what i can do to make my lawn look better. Thanks
