Impact of Winter Weather on Plants
De-icing products also pose a threat to landscape plants. De-icing products are salts and they can damage plant roots and foliage when they are splashed onto leaves or dissolve in melting snow and run into planting beds. Salt damage can burn evergreen leaves, dry out bud scales and result in damage to the upcoming season’s leaves and flowers. Salts in the soil can displace other minerals resulting in nutrient deficiencies and interfere with water uptake by the roots. The chloride ions from rock salt can be transported within the plant causing leaf burn and die back. Some of these problems will not be obvious until later in the growing season or periods of drought stress.
