These harsh chemicals run off of sidewalks, walkways and driveways and burn adjacent grass and other vegetation. After winter weather is over, it's a good idea to evaluate your yard to see where salt may have affected grass and vegetation in your yard so that you can take the necessary steps to reverse any damage.
The best offense is a good defense; preventing or lessening salt damage is the most effective way to keep salt and de-icers from hurting your lawn. During winter, try not to use de-icing salt (sodium chloride) — or use it sparingly. Use calcium magnesium acetate, which is the most environmentally safe product to remove ice. It is allegedly as corrosive as normal tap water. You can also use burlap screens, plastic fencing or snow fencing to protect areas of your yard adjacent to roadways from salt spray and snow buildup.
