Gardening Speakers’ Guild
Does your garden club need a speaker for an upcoming meeting? Want to arrange a talk at your local library? Request a speaker here.
Ask an Expert is another way for you to get answers from the Oregon State University Extension Service. We have experts in family and health, community development, food and agriculture, coastal issues, forestry, programs for young people, and gardening.
To receive the best possible answer to your gardening question, please provide as much information as possible. This includes bringing a sample of the plant (or insect, spider, etc.) with which you have a question or concern into your local OSU Extension office. If it is not practical for you to bring a sample into the Extension office, please provide a photograph of that captures the plant or section or your yard with which you have a question or concern. A wide angle photograph and a close up are helpful, in many instances. Finally, please allow the Master Gardener volunteers the time that they need to comprehensively research your question.
