Yes, Master

My friend and gardener Nancy Sakaduski alerted me that applications are being taken for the 2013 training class of the Chester County Master Gardeners.
 "Penn State Master Gardeners are volunteers trained by Penn State Cooperative Extension to educate the home gardening public on the latest research-based practices in gardening and environmental stewardship," according to the group's press release.
To be selected, you should display "an interest in horticulture and a commitment to complete the required volunteer and educational hours. A Master Gardener trainee is required to attend 42 hours of classes, pass the exam at the end of classes and perform 50 hours of service to the organization."

You can apply to the program by calling the Penn State Extension office at 610-696-3500 or e-mailing the program coordinator at exa108@psu.edu.
