Moving house plants from Canada to the USA
If you are moving from Canada into the United States you will be happy to know that in most cases your house plants will be allowed to come with you. (As stated on the USDA website) Unfortunately I was unable to find a list of common houseplants that are approved for export into the United States. So, just to be on the safe side – we suggest when moving a house plant from Canada into the USA that you apply for a Phytosanitary Certificate from the Canadian Food & Inspection Agency.
You can request a phytosanitary certificate from the Canadian Food Inspection Agency by calling 1-800-442-2342. I left a message in the morning and was pleasantly surprised to get a return call in the early afternoon.
There is a manual on the USDA website listing plants that are under restriction going into the USA – you can view that here Items such as citrus and blueberry plants are strictly prohibited from being exported to the USA, as are several species of bulbs from New Zealand and many invasive grasses.
Unless it is a very special house plant, it seems to me that for the amount of red tape and paperwork it will take – you may want to consider giving away your plants and then purchasing new ones when you arrive in the Untied States…
