Check out this article which happened to appear on the very bottom of our FGRV forum page today! You searched for california inspection - RV Life
We are California natives, San Francisco to be exact, and lived in Boston for six years. My DH is an avid gardener and houseplant devotee. Our homes have always been brimming with houseplants. Well, imagine the reaction of the California inspector when my husband "gunned it" when waved through at the border when we returned home with a car loaded with houseplants (and one caged parrot)! Good thing he had had all the plants inspected, and passed, while in Boston because, sure enough, we received a notice in the mail asking to show proof of inspection.
I suggest you research what you need to do to have your plants pass the California border inspection. Note: It's not very hard. The rules are there for good reason as "California's agricultural abundance includes more than 400 commodities. Over a third of the country’s vegetables and two-thirds of the country’s fruits and nuts are grown in California." https://www.cdfa.ca.gov/statistics/
Best of luck in full-timing!
P.S. All the plants arrived in good shape after the cross-country trek. I might add, that my DH brought all the plants and the parrot inside our motel each night because he did not want them subjected to freezing temperatures in November. Oh, he also let his 8-month pregnant wife inside too! That trip provided us with some great memories as you can imagine.
