Instructions for collecting, preparing and shipping your samples
The Plant Clinic is devoted to our clients and will remain operational until further notice. For the safety of all involved, we request that packages be sent via mail or express delivery if at all possible. Please send us the shipper and tracking number if you ship via an express delivery service so we can track packages and ensure they are delivered quickly from our central University mailing service. If samples are too large to be delivered, please drop them off, with a completed sample form at the NORTH loading dock (accessible from Orchard Ave) of Cordley hall (map view). Please call us (541-737-3472) to let us know a sample had been dropped off, and we will come get it.
Samples can only be accepted from 8:00 a.m. to 4:00 p.m. on weekdays. Please allow extra time for sample processing.
These measures are being instituted to be in agreement with the University's policies, and to keep our customers and employees safe.
The OSU Plant Clinic service fees are increasing, effective July 1, 2020. Our fees have not been increased for at least three years, and are being increased now due to both the rise in minimum wage and increased expenses. The new fees have been updated on our Services and Fees page. Thank you.
We very much appreciate your cooperation! For best service to your growers, for the most useful returns on your efforts, and for the efficient use of your time, please read and observe these instructions before collecting, packing and submitting specimens.
