Just a Dash Will Do - De-Icing Alternatives
Deicing salts applied to your driveway and walkway
may save yourself from neck or tailbone injuries this
winter, but they can spell disaster for your landscape
plants, vehicles and nearby lakes and streams. Much of the
salt flows with melted water into the Rouge River and nearby
lakes. In addition, excessive salt application can affect
plant stems, buds, and roots of trees. For these reasons, it
is important to apply salts only when necessary and in the
appropriate manner.
The most common deicing agent used in Michigan is a
compound called sodium chloride. Sodium chloride causes
severe decline in plant and tree health. Salt runoff can
wash into the soil, thus increasing salt levels. As a
result, the root systems grow week, which reduces the
ability of foliage to fight disease. Salt that is applied
near your home can enter streams directly from the road or
from surrounding melting snow (runoff). A sudden or extreme
change in salinity (or "saltiness") can be harmful to
aquatic life as well. Aquatic organisms require a certain
amount of salt in the water. If the amount of salt is too
great it will affect an organism’s ability to regulate the
amount of fluids in and out of its cells.
You can reduce pollution of local streams, lakes and
landscape vegetation by selecting the proper materials and
methods for removing ice and snow.
- Ice melting products are most effective when spread
thinly and evenly over the pavement prior to ice
formation. It is much easier to prevent ice than to try
and melt a thick layer of ice.
- Use alternatives, such as clean cat litter or
sawdust to help improve traction on ice (sand is NOT
recommended for residential use).
- If possible, use less salt than is recommended by
the manufacturer.
- Add a small amount of water with the deicer to help
initiate melting.
- Protect your plants with burlap or durable plastic
screens to shield them from traffic splash.
- Try using more salt-tolerable plants. Check with
your local landscaper to find out what is best suitable
for your needs.
