Shipping Heritage raspberry plants through the U.S. Postal Service takes some planning. Use light weight packaging to secure the plants in the box. Bare root plants stand up to mailing better than those packaged in soil. Send only healthy plants through the mail. You will need plant health certification from your local extension office to ship plants to Hawaii and California.
Place bare roots (any growing medium has been removed) in damp sterile soil. Do not soak the soil in water, too much water while shipping will cause roots to rot.
Wrap the roots and sterile soil in plastic wrap. Wrap them snuggly, taking care not to crush the roots bringing the plastic wrap up around the base of the plant. Secure plastic wrap with jute twine.
Place a damp paper towel into a large Ziploc-type bag. Place the entire plant into the bag and seal.
Write the name and variety of the Heritage raspberry plant on a label in marker. Place the label on each bag.
Put priority box together and place a 1-inch layer of packing peanuts in the bottom. Carefully place one bag in the box and add another layer of packing peanuts. Leave room at the top of the box for a last layer of packing peanuts.
Seal the box tightly with packing tape. Use Priority Mail to ensure a fast, safe delivery.
