This evaluation will help identify the cause, whether it’s physical damage, disease, or pest infestation. Once the cause is determined, suitable treatments or management strategies can be employed to save the tree from further decline.

  • Apparent causes of bark damage include animal feeding or mechanical injury
  • Canker diseases can cause bark damage without visible signs
  • Accurate identification is crucial for determining the appropriate course of action
  • Seek the assistance of a certified arborist or tree care professional for a detailed assessment and identification
  • Treatments and management strategies can be implemented once the cause is determined.

Common Issue Of Weak Roots In Arborvitae Trees

Weak roots can lead to the premature death of arborvitae trees. This problem often arises soon after planting and affects the tree’s establishment and overall health. Weak roots can be a result of improper planting techniques, insufficient watering, or inadequate soil conditions.

To promote the development of strong and healthy roots, it is important to follow correct planting procedures. This includes digging a hole wide enough to accommodate the entire root system and loosening the surrounding soil to encourage root growth. Additionally, watering deeply but infrequently and allowing the soil to slightly dry out between waterings can encourage deeper root growth.
