The domestic lawn is a typical American landscape feature, but this hasn't always been the case. Lawn grasses aren't native to this continent. They were actually brought here by our early European settlers. The bad news is most manicured lawns are sustained with the use of fertilizers and pesticides, chemicals suspected of contaminating our water and our environment. The good news is that there is a movement towards more sustainable lawns using organic fertilizers. I've done it right here in my own yard. Great lawns can be achieved without negatively impacting the environment.
