Putting together a little care package for some friends in Lithuania who like to garden. I'm only putting one cutting in the package along with some other souvenirs and plan to ship using USPS. I purchased the cuttings from a local walmart and the package says: APPROVED FOR EXPORT, EXCEPT TO ARIZONA. I can't find the answer on USPS but I'm guessing they'll be ok to ship internationally? Anyone have experience with shipping cuttings to Europe? Is it okay for me to tape and wrap the package before going to the post office or will I have to open it to show the clerk?
