Will road salt kill the plants in green infrastructure practices?
Green infrastructure practices, especially those located next to streets or sidewalks, should be designed with plants that are salt tolerant. They are also designed with well-drained soil that helps flush salt through the soil more rapidly and reduce high concentrations that negatively affect plants. Thus, road salt rarely kills the plants, although it can cause stress and damage if used in large quantities. To reduce the potential for any damage, you can choose eco-friendly salt alternatives such as calcium chloride, which is safe for plants and pets, or you can reduce the amount of salt spread.
