Growing a Greener Grass

The sorry state of my front and back lawn and the warmer temperatures have me researching the best ways to organically fertilize and grow grass so our house can look nice and tidy come spring and summertime. What kind of grass did you think I was talking about? I choose organic and to avoid pesticides for my health and the health of our environment. I found some tips here that I plan to implement.
