In this Washington Informer article, Lou Meyer from Davey's mid-Atlantic region shares how rock salt overuse can negatively impact trees.
Since 1938, U.S. residents have used rock salt to prevent roads from freezing after winter storms, and while it is necessary to ensure public safety in icy conditions, homeowners and winter maintenance staff must be mindful of the amount they use. 
Although rock salt is an effective tool, causing ice to melt and creating friction between car tires and the pavement, the excessive application of sodium chloride on roads can adversely affect the environment, leaving roadside and landscape plants vulnerable to damage.
If too many trees are weakened due to salt use, the city’s air quality is at risk of decreasing, while pollution could increase. Being reckless with deicers, jeopardizes both the climate control and the amount of oxygen trees offer.
“We have to find that balance of protecting the public while also protecting our green infrastructure,” said Lou Meyer, an arborist with Davey Tree.
