Testing my yard and garden soil

Asked February 4, 2016, 2:19 PM EST

Where can I have a soil sample tested for nutrients and pH? I live in south Salem. Also, my lawn is infested by wild garlic and more worrisome, lesser celandine. I am trying to find a local retail source for Fiesta or another of the new iron-based broad leaf herbicides.

There are several laboratories that can test your soil at reasonable cost, a list of which you can find in the OSU Extension publication EM 8677, Laboratories serving Oregon. The URL to access the publication is below:

Wild garlic is very problematic to control in lawns as can be Lesser celandine. I looked up a sample label for Fiesta but did not see either of these weeds listed as
controlled by this product. Although it appears to be a "low-risk" ingredient, it was not apparent from the label that it was specifically available in homeowner packaging. I unfortunately have no way of knowing if it is and where it can be purchased.
Some information on Wild garlic from the PNW Weed Management Handbook is in the URL below.
As far as I can see only the 2,4-D would be available in homeowner packaging.
Information on control from the Noxious Weed Board in Washington is below.
Please feel free to contact me directly for more information on these weeds.
