During the winter months, hundreds of thousands of tons of deicing salt is used to make roads and sidewalks safe. Unfortunately for plants, salt is the enemy and can cause serious damage or kill them outright. When choosing plants for landscaping near sidewalks and roads, look for salt-tolerant plants. These are identified in many online directories of plants that are appropriate for your region. For people in warmer climates near the ocean, these same plants can also be perfect for your garden when marine winds carry salt-laden breezes your way.
