Winter transforms the world into a picturesque scene of snow-covered landscapes and frosty mornings, but it also brings the challenge of keeping driveways, sidewalks, and pathways free from dangerous ice. Deicing agents are often the go-to solution for making surfaces safe. However, after 20 years of experience at Cutting Edge Landscaping, we’ve seen firsthand that while these agents are highly effective at melting ice, they can inadvertently damage your lawn in the process.
In this post, we will walk you through everything you need to know about deicing agents, how they affect your lawn, and what you can do to keep your yard healthy throughout the frosty season.
Deicing agents are chemical substances that lower the freezing point of water, melting ice and loosening its bond with the surface it’s on. They come in different forms, such as salt-based products like rock salt, calcium chloride, and magnesium chloride, as well as non-salt options like urea and potassium acetate.
These agents attract moisture from their surroundings and form a brine solution that melts the ice. This process is known as the “freezing point depression” effect. While this makes them highly effective at melting ice, they can also draw out moisture from other sources – including your lawn.
When deicing agents come into contact with your lawn, they can leach out the moisture and essential nutrients your grass needs to thrive. This can result in a condition known as “winter desiccation,” where the grass dries out and turns brown. In extreme cases, this can even lead to permanent damage or death of your lawn.
Moreover, salt-based deicing agents can also have a chemical effect on soil structure, making it more difficult for plants and trees to absorb water and nutrients. This can create an imbalance in the ecosystem of your yard, leading to further issues down the line.
1. Yellow, Brown, or Dead Patches:
Discolored patches are a clear sign of salt damage. Grass exposed to high salt levels often turns yellow, browns, and dies in certain areas. These patches usually appear near sidewalks, driveways, or roads where deicing salts are used. To check if salt is the cause, note if the damage is near areas with deicer runoff. Inspect the soil for a crusty texture or visible white salt deposits, which indicate salt stress.
2. Wilted Grass Blades:
Deicing agents can dry out the soil, leaving grass dehydrated. Salt-damaged grass may look limp and weak, even after rain or watering, and blades may feel brittle or appear scorched. To confirm salt damage, check the roots. If they feel dry or crumbly and the soil isn’t holding moisture, salt may be the issue.
3. Slowed Growth and Development:
Salt in the soil can damage roots, making it harder for grass to absorb nutrients and water. This leads to slow growth, weak grass, and thin or patchy areas. If you notice slowed growth along with yellowing or wilting, it’s likely deicing salts are harming your lawn.
By keeping an eye out for these signs, you can take steps to help your yard heal.
While it may seem like there’s no avoiding deicing agents during winter, you can take steps to protect your lawn from their harmful effects.
1. Limit Use:
The most obvious solution is to limit the use of deicing agents on your property. Consider alternative methods such as scraping or shoveling snow, using sand or kitty litter for traction, or investing in a heated driveway system.
2. Choose Alternatives:
If you need deicing agents, opt for alternatives like potassium acetate or calcium magnesium acetate which are less harsh on plants and soil.
3. Apply Appropriately:
When applying deicing agents, follow the instructions carefully and apply only the recommended amount. Avoid over-application and try to keep the product on surfaces rather than letting it spread onto your lawn.
4. Protect Sensitive Areas:
If you have sensitive plants or trees in your landscape near areas where deicing agents are used, consider covering them with burlap or plastic sheeting during winter to shield them from salt exposure.
