CALL AHEAD! 

You may call in advance and the office staff will provide you with the Master Gardener hours for that week or you may leave a message for the Master Gardeners. You may also drop off a sample at the front desk at any time between the hours of 9:00 to 4:00, Monday through Friday. The Master Gardeners will answer your questions promptly within their weekly office hours.

 
*Diagnosis provided is only speculative, to have a confirmed diagnosis of any plant disease, insect, or other plant sample, a sample can be submitted to Iowa State University. 
 

*Due to the Iowa State University Soil Lab closing the Master Gardeners and Dubuque County ISU Extension and Outreach can no longer take soil samples for submission.  We do offer a test kit to send only lawn and garden soil samples to the University of Minnesota.  All farm samples are to be sent to labs certified by the state of Iowa.  We offer resources to ag producers on how to do this as well.
