What can I plant on my drain field?
Generally you want to use plants with a shallow root system that can be mowed or maintained. Trees and shrubs should be planted at least 10 feet away. Washington State University (WSU) has some written information on landscaping over drain fields.

If you have a specific plant you want to know about you can call WSU at 360-379-5610 and leave a message for a Master Gardener. They can tell you about the particular plant and if it would be appropriate.
