Attention Seed Buyers from outside Canada

Some countries require that phytosanitary certificate  accompany seeds entering their jurisdiction. You can check with your country's Plant Import Department regarding tree seed import regulations. If required, each species ordered will need a separate certificate.

We can obtain phytosanitary certificates but there is a charge of $20 per species.
Please search for Phytosanitary Certificate under "What are you looking for?" see below

In the United States the buyer must obtain and provide a Small Lots of Seed Permit to GreenTree Agroforestry Solutions before the order will be shipped. This permit can be obtained through the APHIS-USDA website

NO PHYTOSANITARY CERTIFICATE IS REQUIRED FOR SEEDS SHIPPED WITHIN CANADA
