The Jackson County Master Gardener Plant Clinic is a research-based diagnostic facility staffed by Master Gardener volunteers in Jackson County, Oregon. We help local residents recognize the nature of their plant or insect problem (including identification) via diagnosis using non-biased, research-based information. We then provide recommendations to manage the disease or disorder using proper control methods, including cultural, biological and chemical measures.

To receive the best possible answer to your query, you should:

  1. Provide as much information as possible regarding your inquiry, including the problem itself, when the problem started, and information about the associated environment.
  2. Provide a large, live sample of the plant or a clean, complete insect sample. For identification, a physical sample is required. For plants, bring large examples (i.e. leaves and branches, flowers if the plant is blooming) of both healthy and affected tissue.
  3. Bring multiple parts of the plant if possible. For example, if you have affected apples, bringing a sample of a branch with leaves will help us to identify the problem.
  4. Provide photographs to accompany physical samples of the plant to help describe the environment and how the whole plant looks, especially if it is a tree or large shrub. It is more difficult to accurately identify a plant or insect solely with photographs. Physical samples will increase the probability of making an accurate identification.
  5. A Master Gardener volunteer will research an answer to your question, using a variety of library and online resources. Master Gardener volunteers exclusively use non-biased, science-based information in their research to ensure that you receive a high quality answer. They will reply to you as soon as they can (volunteers do not make diagnoses on-the-spot, time is needed to perform research).
  6. OSU Master Gardener Plant Clinics accept clean plant (live, dead or preserved), arthropod (dead or preserved) and soil specimens for assessment. Safety of the volunteers is paramount. For this reason, the Master Gardener Plant Clinics will not accept swabs, tissues, hair or other specimens of human or animal origin; articles of clothing, bedding or towels; personal hygiene items such as toothbrushes, hairbrushes or any other items that may be contaminated with human or animal pathogens, parasites or secretions. Clients with questions about possible human or animal health need to direct those inquiries to the appropriate public health or veterinary experts in the community.
