Obtain permission to propagate source materials in the USA

According to the service agreement between the customer and FPS, the customer (not FPS) is responsible for obtaining permission to propagate all tree materials submitted for custom services. It is a good idea to have a written record of this permission. The FPS service agreement states that "The Customer hereby represents and warrants that it has legal title to, and has the right to propagate the Selection(s) submitted for custom services."

Submitting Plant Material

Please note that, if you are unable to send the requested number or size of cuttings, the treatment/testing period may be significantly extended to prepare the additional needed propagations for pathogen testing purposes.

When submitting budwood please collect 25-30 fresh, fully dormant hardwood cuttings from a single source tree for each variety/selection to be supplied. The optimum size for the cuttings is 12" (30cm) long and 1/4" (9 mm) in diameter. If you are unable to supply the optimum number and size of cuttings, please send all of the cuttings of all sizes that can be collected from a single source tree for each variety/selection. Each bundle of cuttings from a single source tree must be bundled together and labeled with variety name and source location (if known). The cuttings should be enclosed in a sealed plastic bag with a very small amount of moisture, packed in a rigid cardboard box or tube, and kept in cold storage until the day of shipment.
