Is there really a way to maintain a lush, healthy, pest-free lawn
without using risky pesticides? More and more natural gardening
advocates are saying yes, it IS possible. If you have ever felt uneasy
about using chemical pesticides, today's column is a must-read!

Pesticides are, quite obviously, poisons intended to kill insects.
However, most pesticides affect vital biological processes that are not
unique to the target pests, according to an organization called the
Safer Pest Control Project (SPCP), based in Chicago, Illinois.
Pesticides can also be harmful to beneficial insects such as ladybugs
and praying mantises that are part of a lawn's natural defenses.
Also affected are microorganisms, the little guys that break down
organic matter that nourishes your soil.
