I looked into it before moving, but then decided to give my plants to family. I get to see them when I visit. My rubber plant went from 10 inches to 7+ feet under my mom's care.
It didn't seem too complicated to get the certificates, but I simply didn't have the bandwidth to deal with it. Also, they were not big/old plants, and the extra cost was hard to justify for some of them.
Please come back to let us know how it went, should you decide to do it.
Bon déménagement!
