Winter deicing efforts can take their toll on your lawn, as rock salt and other ice-melting agents frequently leach into the soil, harming grass and interrupting its growth.

If you have been using salt to melt the ice on your lawn, you must be wondering if the grass will grow back after the salt, right?

Whether your grass grows back depends on the severity of the salt damage and the type of grass on your lawn. If there is only slight damage, your grass will most likely regrow.

What does salt do to your lawn?

Salt from deicing chemicals can wreak havoc on your lawn, particularly when it accumulates in the soil. Some of the ways that the salt can ruin your lawn include:

Dehydrating the grass: Salt in the soil draws moisture from the grass blades and roots by osmosis, causing dehydration. It causes the grass to wither and die through “physiological drought,” even when there is enough water in the soil.

Toxicity issues: Grass does not require salt or chloride for growth or any other metabolic activity. So, once in the soil, they can quickly accumulate to hazardous levels in the grass, bringing detrimental consequences. They can also harm the lawn’s roots, reducing its ability to absorb water and nutrients.

Nutrient deficiency: This occurs when excess sodium competes with ions such as magnesium and calcium for attachment sites on soil particles. When sodium substitutes for these cations, they become less available for plant uptake, leading to nutritional deficiencies.

Reduces plant defence: Excess salt, along with the other effects listed, causes stress on your grass. A stressed grass is unable to resist diseases and insects, and it is less tolerant of drought and heat.

You can tell you have salt damage in your lawn by brown or discolored grass, obvious patches of dead or thinning turf, delayed spring green-up, a wilted or dry appearance, and white crusty residues on the soil surface.

These signs are often more visible along the edges of sidewalks, driveways, and roadways, where salt collects as snow melts and runs off.

How can you prevent salt damage on your lawn?

To increase the chances that your lawn grass will grow back after winter, you need to protect it from salt damage. Some of the ways to do this include:

Use safer options

One of the best ways to protect your lawn from salt damage is to use alternatives to conventional rock salt, which contains sodium chloride. Alternative deicers may be more expensive, but you will save money fixing your grass next spring.

Magnesium chloride, calcium chloride, and potassium chloride are among the most common options. You can also use sand or other abrasive materials, such as kitty litter for salt, or mix salt with them instead of using a straight deicer.

For a great experience, use a concrete-based, pet-friendly ice melt. It contains no salt, chlorine, or acetate; it is safe for the environment, your puppy, and the grass and flowerbeds, driveway, and sidewalk.

If you’re laying new concrete, consider having a heated driveway and sidewalk. They usually use electric coils or a boiler system to circulate a mixture of hot water and propylene glycol through subterranean pipes.

The device heats the pavement and melts the snow. A heated driveway installation can be a little costly, but it will be worth it in the long run.

Minimize your salt usage.

Apply rock salt or deicers sparingly to avoid overapplication. While a little is fine, too much isn’t always preferable.

Rather than salting the entire driveway or sidewalk, focus on specific ice patches.

Use around a handful of salt per square yard, no more.

Use a handheld or push spreader to apply salt evenly to surfaces. Using it this way reduces waste.

When the temperature is too low, avoid salting. This is because traditional rock salt (sodium chloride) is generally useless when temperatures fall below 15 to 20 degrees Fahrenheit.

You should shovel or use a snowblower early and frequently during a storm to keep snow from compacting into ice. The less ice that forms, the less salt you will use, hence the lower the chances of damaging your lawn.

Go with salt-tolerant grasses.

Depending on where you live, choose more salt-resistant grass varieties. If you must apply salt, a salt-tolerant grass will suffer less damage, which will be great for you.

Perennial ryegrass, tall fescue, and creeping red fescue are the most salt-tolerant cool-season grasses that you can plant in the northern areas. They have modest salt tolerance, which is inferior to some warm-season turfs but superior to Kentucky bluegrass.

Salt-tolerant warm-season grasses include seashore paspalum, Bermuda grass, and St. Augustinegrass. These grasses thrive in the South (where snow is uncommon), but you can also find them in some transition zone areas with cooler winter temperatures and snow.

If you want salt-tolerant alternatives to grass, consider American holly, bearberry, cotoneaster, English yew, false cypress, and littleleaf boxwood.

Their ability to survive saline environments (i.e., salt) makes them ideal for planting in strips between your driveway, sidewalk, and lawn.

Protect the soil

To protect your soil and grass, apply a thin layer of mulch or finished compost along the margins of your driveway or walkway.

You don’t need to go wild with compost or mulch. Using 2 to 3 inches of mulch and 1/4 to 1/2 inch of compost is enough. This covering of organic material will help to “trap” the salt rather than allowing it to drain down into the soil and harm the grass.

When spring arrives, you can rake it up and dispose of it, or use it in areas where salt damage is not an issue.

Flush the soil regularly.

When the ground isn’t frozen, use your garden hose to remove as much salt as possible from the root zone. Turn on a setting akin to a rain shower or a shower head to distribute water in a natural pattern with minimal effort. The water will drive sodium deeper into the soil, beyond reach of your lawn’s roots.

This process requires a large amount of water. You should water the entire area until water pools on the dirt. Allow it to soak in, then repeat three or four times.

Apply gypsum to your lawn.

Gypsum, or calcium sulfate, is the most effective soil addition for “knocking” salt from soil particles and organic materials. The calcium in gypsum replaces the sodium on soil particles, allowing the sodium to combine with the sulfate and produce sodium sulfate.

Sodium sulfate quickly dissolves in soil solution, and you can easily flush it or leach it from the root zone.

For a great experience, apply the gypsum at a rate of 20-40 pounds per 100 square feet of soil. After application, rinse the soil with plenty of water to remove the sodium sulfate from the root zone.

The calcium in gypsum displaces salt residues, reducing the uptake of harmful salts through the plant root zone. For optimal results, use pelletized gypsum in your lawn spreader and make two runs (full open rate) around street curbs, driveways, walkways, or anywhere an ice melter will be used frequently during winter.

Avoid salting near grass.

When applying deicers to your driveway or sidewalk, keep a 12 to 18-inch buffer zone from the edge of the concrete. Once the product has worked in the center sections, use a snow shovel or square-point shovel to remove the ice nearest to the lawn.

Disperse snow piles.

If you are not removing snow from your property, avoid stacking it in one location. The more snow that remains in one location, the more salt residue may later combine with it and run off into your lawn, resulting in a concentrated area.

Dispersing snow piles does not remove salt, although it does help to dilute amounts in runoff water.
