However, when 'salty' snow is shoveled off walkways, onto the lawn or shrubbery, you might see evidence of injury when spring arrives and growth begins.
Salt spray can injure buds and twigs causing bloom failure in flowering plants and misshapen shrubs.
Salt that enters the soil may not show its' impact on plants for several years. In extreme cases, soil salt concentration may cause soil structure to degrade. A soil or tissue test may help you decide. Soil should be tested as soon as possible following spring thaw. The youngest most fully mature leaves of suspect plants should be sampled midsummer.
