I have a Black Hills Spruce about 10 feet tall that I think is dead due to a lawn service spraying for. Broad leaf and fertilizing my lawn during windy conditions leaving several streaks in my grass and later showing up in the spruce tree. The lawn service at first stated they would take responsibility if it died and now they don't. Do you have a way of testing the branches for chemical damage and if so what do I have to send you? Thanks Jerry Rothstein

Thank you for the question. We suggest you contact a certified arborist to come and look at your tree. If it's not dead, you will get accurate advice on possible problems and what can or cannot be done about them. Some herbicides can damage trees and the arborist can help determine if this is the cause of the problem or not. This link provides useful information on hiring certified arborists: http://www.extension.umn.edu/garden/yard-garden/trees-shrubs/how-to-hire-a-professional-arborist/

You may want to contact the MN Dept of Agriculture if you have a specific complaint about your lawn service. Here is their link: http://www.mda.state.mn.us/

Here is a good publication about diagnosing herbicide injury: https://www.extension.purdue.edu/extmedia/id/id_184_w.pdf
We don't know who might do chemical herbicide analysis of dead or dying plant tissue.

Thank you for contacting Extension.
