Copper Sulfate vs Rock Salt for tree roots in sewer line?
Home Depot etc. sell copper sulfate crystals for tree roots in sewer lines. Plumbers seem to recommend rock salt for the same purpose. Everyone seems to agree that copper sulfate works better. But does that take the cost into account? Ten pounds of copper sulfate might be a lot more effective than ten pounds of rock salt, but is $10 worth of copper sulfate more effective than $10 worth of rock salt?

- Copper sulfate is the best approach for this hands down.
- i have used the rock salt and it kills the roots your choice
