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 West or North loading dock 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 10:00 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.
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.
