Plant Clinic Information - For Master Gardener Advice

We are happy to answer questions about gardening, orchards, landscaping, composting, garden insects, plant diseases, or related topics. If you would like us to diagnose a plant disease or pest, please bring a sample with you. Our plant clinic schedule varies by month and is listed below.

Getting Your Soil Tested

We have chemicals on back order from the manufacturer so, unfortunately, we are pausing soil testing at this time. When the chemicals arrive we will let you know. We look forward to being of service in the near future hopefully the end of December/January!

In the meantime, if you would like to have your soil tested please follow this link for a list of official list of labs in Oregon.

Soil testing can be done any time your soil isn’t frozen or overly wet. The best time of year for sampling is in the spring or fall. How to take a Soil Sample
