I stopped selling some years back. I was a state inspected nursery. Other than the inspection, all they did was send me one form before the inspection, verifying I did not add other plants (like trees), to my inventory, and that I still had the same amount of land under crop. After I gave it up, I got this big packet with all kinds of info to fill out. Questions such as did I have hazardous material labels on all containers etc - and, since I was not selling, I ignored it. A second one came. I ignored it. I had already informed the state months before that I didn't need inspections because I was out of business, and thought that the part of the government that mailed the big questionnaire had not been notified yet to take me off the list. Turns out I should have read it more carefully - as a very official letter came next. If I remember right (been a few years ago!), they wanted me to appear in person to the State Ag dept. because I didn't fill out the packet. I spent a lot of time on the phone getting it all straight.
I do understand the need for regulation. If they do all this, though, for a backyard daylily sales garden - I can't even begin to imagine all the red tape any regular business must do.
