Using nature to manage landscape pests was the message that one exhibit sought to spread to visitors at the Philadelphia Flower Show, March 4 to 11.

     The main floor exhibit, created by the United States Environmental Protection Agency (EPA) and Temple University Department of Landscape Architecture, demonstrated ways to limit the use of chemical fertilizers and pesticides and still have a successful garden. Using Integrated Pest Management (IPM) practices, the exhibit incorporated a diverse range of native plants and shrubs, animals and bugs that help to build ecological stability.

     According to the EPA, IPM practices can be used as pest control for any kind of garden.

The exhibit followed three basic IPM tips:

1. Use native plants, as they resist pests and diseases. Maintain and restore natural resources, including woodlands, wetlands and streams.
2. Learn the best time to control pests and control techniques. Start by diagnosing the problem and then use the least toxic methods (pruning, hand removal). Attracting and introducing natural predators, using natural pesticides and using insecticidal soaps and oils before trying chemical pesticides can also achieve control.
3. Probably the most surprising is to erect bat or birdhouses, both well-known consumers of insects.

     By preserving, protecting and restoring natural areas and native plants, valuable habitats are created for beneficial insects and animals, and will ultimately benefit surrounding communities and improve the health of the landscape.

     The IPM exhibit at the Philadelphia Flower Show was a collaborative effort between the U.S. EPA, universities, colleges and high schools.
