Native plants for drainage ditch

Asked September 12, 2016, 3:38 PM EDT

We have a drainage ditch shared by 6 homes. We wish to plant native species to both stabilize the banks and provide proper soil retention and flow in the channel. The channel bed is about 10-12 wide, the banks are 6-10 high.

Thank you for submitting your question.

The size of your drainage ditch, or stream, seems large enough to handle native tree species that grow along streams. This typically includes willow, red alder, white alder, Oregon ash and vine maple. You could supplement these with woody shrubs.
I would need to know more details about your specific situation to be able to help you, such as location, stream slope, surrounding vegetation and light conditions.

Feel free to email me to set up a time to visit about details. You may also be interested in calling the Polk Soil and Water Conservation District office. They help landowners with these types of projects, and they may also have grant funding to help. Their phone number is 503-623-9680 and email is They also have a website -

Good luck with your project.
