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 most branches
  • Affected trees leaf out later than other non-infected trees
  • Damage most noticeable in spring
