Continuing Education

The Master Gardener training provides 40 hours of education. Once you complete the volunteer commitment of at least 40 hours, Master Gardener Interns will receive a certificate from Purdue University through their Master Gardener county coordinator that verifies they completed the Purdue Master Gardener Program requirements.

Purdue Master Gardeners must satisfy specific requirements each year to maintain the Purdue Master Gardener Title. They must complete and report a minimum of twelve (12) volunteer hours approved by the Master Gardener county coordinator and six (6) hours of educational training by participating in State, regional, national, or international Master Gardener conferences, county-sponsored advanced training sessions, or any other program approved by the Master Gardener county coordinator. Please note this education requirement was waived for 2020, but is in effect for 2021 and after. In addition, Master Gardeners must undergo a yearly background check.
