I"ll be doing a presentation tomorrow for the Penn State master gardeners. Topic will be growing unusual fruit in Pennsylvania. Wish me luck.

My wifes has a lady friend who's mother is a master gardener.
Its my understanding there are courses one takes for this.
Little bit of info


Master Gardeners are active in all 50 states in the United States  and four Canadien provinces.According to the 2009 Extension Master Gardener Survey, there are nearly 95,000 active Extension Master Gardeners, who provide approximately 5,000,000 volunteer service hours of per year to their communities. Once volunteers are accepted into a master gardener program, they are trained by cooperative extension, university, and local industry staff in subjects such as, Taxonomy, Plant Pathology, Cultural Growing requirements, Nuisance wildlife management , and Integrated Pest Management.
I think there required to participate community servive as well but not exactly sure as it may be different from state to state.

Bass, I took the Master Gardener course here in Indiana years ago. I think that you will be great! Many of the people taking the course with me were pretty much beginner gardeners and a lot of the info that we were given was pretty basic. We had a well know "fruit guy" talking about fruit but still only the common stuff. I would love to come and listen to you talk if I wasn't so far away! Best of luck! (But you won't need it...)
