Extension Master Gardener Volunteers (EMGVs) are recruited and trained to answer questions and diagnose gardening problems for the public. Most states have developed an EMGV Manual for use in the initial training. Thirty-two EMGV Training manuals from across the United States were reviewed for form and content. While many of the manuals have common themes, climate and cultural differences are reflected in regionally specific subject areas. There are a wide variety of manuals to meet the varying needs of EMGV Training programs.
