Arborvitae White Spots

White Spots on Arborvitae usually means one of a few common care issues.

Check light, pests, humidity, and recent stress first. One symptom alone rarely proves the cause.

Check first

  • Is the soil wet, dry, compacted, or sour-smelling?
  • Did light, temperature, or watering change recently?
  • Look under leaves and near stems for pests.

Small fix

Make one change at a time, then wait for new growth before judging the result.

When to cut back

Remove leaves that are fully dead, mushy, or spreading disease. Do not strip every imperfect leaf at once.
