Honestly, Allison, but here in NJ if you want to ship plants west of the Mississippi you must become a certified nursery.......costs $75 and you must have your Greenhouse inspected by the State once a year by State Inspectors. Then when you ship, you put a copy of your certification on the box. Also, If you ship West of the Mississippi you must ship bare root. Sounds complicated but not really. Just a pain in the butt to have the inspections. The regs are like everything else here in NJ. Too many and too much.
I did it because I ran out of room in the Greenhouse and put the plants up on eBay and started to sell them like crazy. I have a blast doing it too. I have time time and enjoy it.
