Deicing salt injury

  • Soil salt damage causes leaf edges or margins to appear burnt or scorched progressing toward the mid-vein
  • Soil salt damage can mimic nutrient deficiencies, e.g., yellowing foliage on deciduous plants
  • Salt spray causes branches to become tuft-like (a.k.a. witches’ broom)
  • Run-off salt kills roots which results in die-back of most branches
  • Affected trees leaf out later than other non-infected trees
  • All deicing damage most noticeable in spring
