Did you know that salt can be harmful to your trees?


Salt can damage trees through 2 means: by means of air-borne salt spray, for example on a busy street, and through the soil. Salt spray that lands on a dormant branch could enter the tissue and kill the bud.

When salt in the dirt liquefies, it separates in to salt and chloride ions. The ions each act in a different way to damage the plant. In very early spring, the chloride ions can be taken up by the roots, enter the sap, concentrate in the shoots, and prevent the buds from opening. Later on, they could be moved to definitely expanding leave and debris margins, triggering leaf scorch, curling, or death. Salt ions make use of the very same “chemical path” as essential tree nutrients. As George Hudler, professor of plant pathology at Cornell explains, the sodium can “tie up the plant’s shuttle system and restrict uptake of magnesium and potassium, two chemicals that are essential for making chlorophyll.” Potassium deficiencies are common in plants suffering from salt injury, states Hudler ( Source : Salt Injury To Roadside Plants) . Salt in the dirt could make a physiological drought. Brine near underground plant origins could be a much more concentrated option compared to the drain in the origins. The roots therefore cannot absorb water with osmosis. Water is so not available to salt-stressed tree that they are actually passing away of thirst.

Identify Salt-Damaged Trees

Salt spray damages could take place in plants that are as far as fifty feet from a quick moving, salted street. Salt spray will harm subjected branches much more adversely than branches covered by snow. Assume soil salt damages in trees that neighbor salted streets and pathways. Trees damaged by salt spray, reveal the greatest damage in early springtime.

Affected trees’ branches may have identifying factors that they are suffering from salt damage, needles end up being yellow or broken, and may break off. Soil salt can trigger the needles of trees to turn a blue-green color. Deciduous trees growing in salty soil may have blossom buds that don’t open. Another sign may be, where frames of the leaf turn prematurely brown in the spring or during hot, completely dry climate. Foliage can be thin, stunted, or yellow and twigs can show dieback.

Keep Your Trees Salt-Free & Healthy

Limit Your Salt Use (near trees)

Avoid salting all the time, not only will you save money on buying so much salt, but you will be mindful of your trees. Only salt when necessary, check your local forecast to determine if ice will be an issue.


Fertilize properly to keep your tree growing vigorously; a healthy tree will manage stress more easily than an unhealthy tree.

Plant New Trees In Appropriate Areas

Don’t plant delicate trees near your driveway or street, these trees will be more susceptible to salt during the winter months.
