In regards to this question:
Hello,

My husband and I are relocating to Fresno in a few weeks, and we are
getting contradictory information about whether or which plants we can take
with us. My understanding is that you can take houseplants that have not
spent time outdoors or at least don't have any critters like fire ants in
them. Does anyone have experience with the border check point and what the
procedure is? I don't want to bring a bunch of plants and then have them
thrown out at the border, I'd rather give them away. Thanks for your help!

until soon, Hope

Good luck on your move, post a message to the group when you get
there.
Here is a page from the California department of Agriculture FAQ page
on bringing plants across the border. There is also a telephone number
for questions at the top of the page:
I've never tried bringing plants across but the last time I drove
through the checkpost, they were very serious and I suspect wanted to
know if Patty Hearst was in the car.

Take care, enjoy the trip.
