Drain field and planting
Where do I find info about what I can plant near my drain field
Chelan County Washington
Here is a publication from eastern Washington that may help http://ext100.wsu.edu/spokane/wp-content/uploads/sites/14/2015/03/C081-Landscaping-a-Drain-Field-15a...
There are a few good references at the bottom of the publication as well.
If you need more assistance contact your local WSU Extension office http://ext100.wsu.edu/chelan-douglas/ or a neighboring county http://ext100.wsu.edu/spokane/. If that doesn't work please contact me again.
