Cooperative Extension Services: Your Local Gardening Experts

What Is a Cooperative Extension?

In 1914, the U.S. Department of Agriculture partnered with a nationwide network of universities to create a system of “extension” services. The goal of these services was to provide farmers across the country with advice from local experts regarding all things agriculture and farming. 

The program was a huge success, and today, there are extension services in all 50 states (though some are not associated with the USDA). Extension services routinely put on community events, hold lectures and courses, and answer gardening and farming questions from locals. Typically, an extension service has a “home base” located at a prominent university in the state but will often have a series of county offices, too.

Contact your state’s extension service for advice on gardening. They can help you with anything from dealing with local pests to choosing plant varieties suitable for your area. You can also get your garden soil tested (usually for a small fee), enroll in a Master Gardener program, or get your child involved in a 4-H club through the extension service.
