Query: The Impatient Gardener

I started using this book in mid summer and so far I have been amazed. I purchased a house that had nothing but weeds in the back yard. I hired someone to get rid of the weeds and all they did was kill what little grass there was. A friend gave me The Impatient Gardener and I started doing what it recommended and now I have a yard full of grass. My next door neighbor came over to find out what I had done to make the grass grow. I plan on giving her the book for Christmas.
