Well, just to toss in my little bit. I AM an OSU certified Master Gardener, retired. I would never call myself a Garden Master, LOL. I did all the training and volunteer time required and then way above and beyond. I don't go around dropping that into all my conversations although there was a time when I brought it up more often as it was part of our mission to spread the message.
Being a Master Gardener never meant we knew all the answers or had all the skills, only that we were taught where to go to find them and given the tools to use to figure them out.
My houseplants always died, then as well as now. LOL We can't all be good at everything. :D
