Many common plant problems can be identified through the exchange of digital images / video so we strongly encourage our member gardens to engage their diagnosticians via email prior to submitting a physical sample. They will provide guidance on what type of documentation would be most useful and whether or not a physical sample is necessary for identification.
That said, please complete the following webform whenever and whereever you are submitting a sample for diagnosis so that we can document the contribution that public gardens are making to our knowledge about plant pests and diseases. After you have entered the information about the sample here, click "submit" and a packing slip will be emailed to you from "SPN Network". Please print and include this packing slip, along with the sample submission form from your diagnostic lab, when sending in your material.
