Hold on...
Brussel’s does import trees from time to time. I the past, I know of an individual they did import for, but he funded their whole import operation. To the tune of hundreds of thousands of dollars. I believe that individual does his own importing now. Meanwhile, Brussel’s imports for their own account using their contacts in Japan.
If you want to buy one of their imported trees, you can. They have a separate quarantine greenhouse where they are kept until they can be released. Usually two years. If you go there, you can visit the quarantine greenhouse, and pay a deposit on a tree. When it has been there long enough, you can come back and get it. If it dies while in quarantine, Brussel’s will refund your money.
Importing trees from Japan is not a trivial matter.
Now, I have given you a lot of information about how it’s done. I sense a bit of “attitude” on your part. In these matters, it’s very important to learn the procedures and find out the proper way to go about these things.
