Each year, Idaho gardeners by the hundreds make a very special commitment to their neighbors, their communities, their environment and themselves.  They agree to give at least 50 volunteer hours where they share their knowledge with others. In return, they get 50 or more hours of intensive, fast-paced training from UI Extension.  Class begins in September and goes  through April.
