Ice melt products are commonly used during winter to keep sidewalks and driveways clear, but many can be harmful to lawns and gardens if not selected or applied properly. According to lawn care experts, the safest options for vegetation are calcium chloride-based ice melts, with magnesium chloride also being a good alternative when used correctly.
Sodium chloride, or rock salt, is the most widely available ice melt but poses significant risks to plants. It can dehydrate plants by drawing moisture from them as they absorb salt through their roots. This effect is especially problematic in winter months when evergreens are already vulnerable to dehydration.
“Some ice melts, especially chloride-based salts can be harmful to your plants and your lush beautiful lawn,” states the release. “The most common ice melt is rock salt or sodium chloride… But it is actually pretty harmful to plants and your lawn.”
Salt exposure does not only threaten plant health; it can also damage concrete and flagstone surfaces. For those seeking safer alternatives, experts recommend avoiding all salt-based products in favor of calcium chloride, potassium chloride, or magnesium chloride blends.
When applying any type of ice melt near vegetation, proper usage is critical. Experts advise removing snow before spreading ice melt since these products are designed specifically for melting ice rather than snow accumulation. Pre-treating walkways ahead of forecasted snowfall can improve effectiveness while reducing the amount needed—thus lessening environmental impact.
“In the spring, when the ground thaws, you want to consider ‘flushing’ your lawn or garden in the areas that may have been exposed to any ice melts you have used,” recommends the release. This practice helps dilute residual chemicals in soil and reduces potential harm as growing season begins.
Certain types of grass—such as perennial ryegrass, fine fescue, and tall fescue—are more tolerant of salt exposure than others. However, evergreens remain particularly susceptible during colder months due to natural wilting processes that increase their risk of dehydration.
While professional snow removal services often prioritize speed over environmental concerns when choosing an ice melt product—38% surveyed cited performance as their top consideration—homeowners concerned about plant health should discuss alternative options with service providers or handle applications themselves using recommended materials.
Ultimately, selecting a calcium chloride-based product and following best practices for application will help protect both hardscapes and landscaping investments throughout winter months.
