When winter hits, the battle against snow and ice begins, especially on driveways, sidewalks, and patios. But while you're focused on safety, it’s also important to consider the impact on your plants. Many traditional ice melts contain harsh chemicals like calcium chloride and sodium chloride, which can damage plant roots, foliage, and soil structure. Fortunately, there are ice melts available that are gentler on your landscape.
Magnesium chloride is a popular option that is less harmful to plants. It works effectively at lower temperatures and is less corrosive to concrete compared to other salts. Calcium magnesium acetate (CMA) is another plant-safe alternative. CMA is biodegradable, non-corrosive, and does not harm plants or soil. It works by preventing ice from bonding to surfaces rather than melting it, making it an eco-friendly choice.
After the storm has passed, it’s crucial to deal with snow and ice buildup on concrete surfaces properly. Shoveling snow immediately after a snowfall is the best way to prevent ice formation. Use a sturdy, non-metal shovel to avoid damaging the concrete. If ice has already formed, a gentle ice melt like magnesium chloride can help break it down without harming nearby plants.
For extra protection, consider applying a concrete sealer before the winter season. Sealers create a barrier that prevents water from penetrating the concrete, reducing the risk of freeze-thaw damage. After spreading ice melt, be sure to remove any excess once the ice has melted to avoid overapplication, which can still lead to plant damage.
By choosing plant-friendly ice melts and taking the right post-storm steps, you can keep your walkways safe without sacrificing the health of your landscape.
