Caring For Your Lawn
Although herbicides and pesticides can provide a "quick fix, " these chemicals don't do anything to improve the health of your yard or garden in the long run. They can actually cause problems over time as beneficial plants and insects are eliminated along with undesirable ones. Furthermore, herbicides and pesticides pose health hazards to your family and pets, and if they get into groundwater they can move around the community and affect local people, plants and wildlife.
The United States Environmental Protection Agency provides this page with information on how to create a healthy garden with minimal or no use of synthetic chemicals.
