Garden Pests & Diseases


Free Garden Problem Help Available

WSU Master Gardeners provide free advice and help with garden and landscape problems. If you have a plant or insect problem, a sample of the affected plant or the insect will help us diagnose the problem accurately and make a management recommendation for you.

When bringing a plant, insect, or turf sample for diagnosis to one of the Master Gardener Plant Clinics, failure to provide an adequate sample or complete information about the sample will greatly affect the quality of the diagnosis. The better the sample and the more thorough the information… the more accurate the identification and diagnosis of the cause and the better the advice on the management or control of the problem. When you submit a sample you will also be asked to complete a form about your plant or insect problem. Procedures on submitting a sample.
