I am not a master gardener, but my mother was. It was mostly her tending to community gardens and volunteering her time. There was classes she attended, but I'm not sure if she learned as much as a person should.
		
		
	 
I was told that after you get your Master Gardener certification, you have to volunteer at least 50 hours per year helping others. But, there are many ways to get credit for those 50 hours including attending classes and shows, answering gardening hot line questions, etc...
The Master Gardener I talked to today said that mostly the classes on gardening were teaching where to find good resources to answer questions. They don't expect you to know everything, but hope to give you the background so you can look up answers.
OK, so a little bit more on the background of my conversation with the Master Gardener today. I asked her 4 questions on things I am dealing with and she was unable to answer any of them. I think maybe my questions were too specific for her knowledge base, but she was able to take out her smart phone and give me what I thought were reasonable answers a few minutes later. 
But, when I asked her about hügelkultur beds, she had never heard of it! I explained the concept to her and why I wanted to pick her brain, because last year we had a terrible drought and all our normal in ground planting and normal raised beds just dried up and died. The only produce I got was from my hügelkultur raised beds and she had never heard of it.

 At that point, I think she realized that maybe I knew more about gardening than she did, and that is when she asked me to consider becoming a Master Gardener because they need more people to help them out. I told her that the more I learn about gardening, the more I realize I don't know near enough. She actually liked that answer and said that is exactly what they want from their members.
	
		
	
	
		
		
			I'm not a club joining type of person, so I stayed away.
		
		
	 
Yeah, I don't live in town and really don't belong to any clubs either. I never thought of being a Master Gardner was like joining a club, but maybe it is.
	
		
	
	
		
		
			My mother did meet lots of nice people, and enjoyed it when she was younger. For the right type it's a great program.
		
		
	 
Thanks for your feedback. Don't know if this is a direction to go for me, or not. Hope to hear some other thoughts from other people before I make any decisions.
