If you contact us with questions about plant problems in the Pacific Northwest, please include your name and location (city, state, and/or county) so we can help you better. In most cases, your local Extension office (in the USA) will be more helpful as they are more familiar with local conditions.
Information in the handbook is in a constant state of change. New information is added and existing information is updated. With so many changes and people involved, there is always the possibility of error. We appreciate being informed of any errors that you may detect. Suggestions for improvement are welcome, also. We have worked to make this book responsive to the needs of the people who use it and will continue to strive for that in the future.
