by

Arborvitae hedges are a popular choice for privacy screens and decorative borders in many gardens. Their lush, evergreen foliage provides year-round beauty and a natural barrier. However, like all plants, arborvitae can develop problems that threaten their health and appearance. Recognizing these issues early and knowing when to call a professional can save your hedge and ensure its longevity.

Common Problems with Arborvitae Hedges

Understanding the common issues that affect arborvitae can help you identify symptoms early. Here are some of the most frequent problems:

  • Discoloration: Yellowing or browning foliage
  • Wilting: Drooping branches despite adequate watering
  • Fungal Diseases: Powdery mildew or root rot
  • Pest Infestations: Spider mites, bagworms, or aphids
  • Animal Damage: Browsing by deer or rabbits
  • Environmental Stress: Browning due to drought or harsh weather

Signs You Need a Professional

While some minor issues can be managed with home remedies, certain signs indicate it’s time to seek professional help. Call a certified arborist or landscape specialist if you notice:

  • Progressive and widespread dieback: When large sections of the hedge are dying
  • Persistent fungal infections: That do not respond to treatment
  • Severe pest infestations: Especially if pests are resistant to pesticides
  • Root problems: Signs of root rot or soil compaction
  • Structural damage: Broken or severely damaged branches that compromise the hedge’s stability
  • Unexplained decline: When the health decline cannot be attributed to obvious causes

Preventive Care and Maintenance

Regular maintenance can prevent many problems. Here are some tips:

  • Water properly: Deep watering during dry periods
  • Prune regularly: To remove dead or diseased branches
  • Monitor for pests: Early detection can prevent infestations
  • Fertilize appropriately: Use balanced fertilizers in spring
  • Mulch around the base: To retain moisture and regulate soil temperature
  • Inspect for signs of disease or pests: Regularly check your hedge

Conclusion

Maintaining a healthy arborvitae hedge requires vigilance and prompt action when problems arise. While some issues can be managed with DIY solutions, consulting a professional ensures proper diagnosis and treatment. Don’t hesitate to seek expert help to preserve the beauty and function of your hedge for years to come.
