Deicing salt injury

  • Soil salt damage causes leaf edges or margins to appear burnt or scorched progressing toward the mid-vein
  • Run-off salt kills roots which results in die-back of branches
  • Affected trees leaf out later than other non-infected trees
  • Damage most noticeable in spring and the summer growing season

  • Foliage sometimes turn brown around the edges but more commonly turns a dull, gray-green color
  • Dried brown to gray-green leaves hang on the tree or foliage drops unseasonably and litters the ground under the tree
  • Severe drought stress may cause dieback of individual branches starting at branch tips
  • More information on watering trees and shrubs
