Many lawns don't require fertilizing. If a soil test shows that yours does, follow recommended application times and amounts. To develop a deep, drought resistant root system, water infrequently and deeply, preferably in the early morning, to save water that would otherwise evaporate. Find alternatives to chemical pesticides for your lawn. Despite your best efforts, your garden may develop some pest problems.
Insects are a natural part of a garden ecosystem.
Employ treatment only if a pest is doing unacceptable damage or threatening to take over. The goal is to control it with minimal disruption of other species. Consumers can send powerful signals. Support natural methods of growing fruits and vegetables by buying organic produce. If it's not available at your local grocery, ask to have it stocked.
