Hereof, what does copper sulfate do to tree roots?
Copper sulfate will kill not only roots growing in the sewer line but also the organisms which produce offen- sive odors. Tree roots in contact with or immersed in copper sulfate solution absorb copper for a short distance into the root system. Use of this treatment has yet to cause the loss of a tree or shrub.
The first method is to pour sodium chloride or copper sulfate, or rock salt, into your toilet. Pour a half pound of the salt into your toilet and flush as many times as you need to clean out the bowl, and repeat this process until you've flushed 2 pounds of salt into your pipes.
