What Is a Zombie Tree and How to Tell If You Have One

A zombie tree is a tree that appears to be alive but is actually dying or already dead. While its branches may still have leaves, and its trunk may seem sturdy, the internal structure is compromised, making it a potential hazard. These trees often linger after suffering from disease, pest infestations, or storm damage, giving the illusion of life while slowly deteriorating.

Signs You May Have a Zombie Tree

  1. Brittle or Peeling Bark – Healthy trees have flexible bark that stays attached. If the bark is peeling or falling off, it could indicate decay.
  2. No New Growth – If your tree isn’t sprouting new leaves or buds in the growing season while others around it are, it may be dead.
  3. Mushrooms or Fungal Growth – Fungi at the base of the trunk or on the bark suggest internal rot.
  4. Hollow or Cracked Trunk – A hollow or split trunk weakens the tree’s structure, increasing the risk of falling.
  5. Dead or Falling Branches – Excessive dead limbs or branches breaking off easily indicate declining health.
  6. Leaning or Unstable Base – If the tree is leaning more than before or the ground around it appears raised, its roots may be compromised.

What to Do If You Have a Zombie Tree

If you suspect a zombie tree, consult an arborist for an assessment. Ignoring the problem could lead to falling limbs or total collapse, posing risks to property and safety. Regular tree maintenance and early intervention can prevent trees from becoming hazards.

By recognizing the signs early, you can protect your landscape and ensure a safe environment for your home and community.
