What are the main differences between synthetic and organic lawn care? Synthetic pesticides and fertilizers destroy the naturally present beneficial organisms in a healthy lawn’s ecosystem. This destruction then transforms your lawn into an increasingly needy “junkie,” requiring more and more chemicals to sustain it. Organic lawn care focuses instead on soil management techniques and long term results, building up the nutrients and organisms in the soil in order to make your lawn better able to withstand drought, pests, and other common problems. Organic lawn care also eliminates damage to the environment and to human and animal health caused by synthetic lawn care products. More Safelawns FAQs
