What information should you provide?
- Personal contact information (address, phone, fax, email)
- Background information on problem:

- What concerns are associated with the plant?
- Completed Plant Identification C0905 (pdf) form.
How much does this service cost?

How should you package your specimens for shipment?
Use a sturdy box for shipping. Wrap fleshy material (such as fruits, bulbs, or tubers) in dry paper towels or newspaper. Wrap any roots in a plastic bag. Include padding to prevent injury during shipping.
