A split tree

Did you notice a huge crack splitting a tree's trunk when heading out? Or a vertical split? Do not worry; you can save your tree. This blog outlines the causes and severity of tree cracks and splits, as well as highlights what you can do if such a situation arises.  

 

Causes of Tree Cracks and Splitting 

It is important to understand what can cause cracks and splitting of trees before we begin discussing the solutions. 

  • Frost in the winter months 

  • Extreme heat during the summer months and sun during winter months.

  • Internal decay or infections 

  • Pest infestations weaken the tree 

 

If a tree falls due to a crack it can significantly damage property and people. To save the tree, understanding the type of crack is essential. 

 

Type of Cracks  

  • Benign cracks: These can significantly weaken the tree and lead to a full-on split trunk.  

  • Frost cracks: These are caused by alternating freezing and thawing temperatures.  

  • Crown cracks: These cracks appear on the upper part of the tree, often due to structural weakness or rapid growth.  

  • Vertical cracks: These cracks run along the tree's trunk and are usually a result of external forces like storms or internal issues such as disease or improper pruning. 

  • Horizontal cracks: These are cracks around the tree's circumference, often caused by mechanical damage, girdling roots, or excessive weight. 

  • Splits or fissures: These are deeper cracks that often appear along the sides of a tree.  

  • Bark cracks: These cracks are limited to the bark layer and may occur due to insect infestations or environmental stress. 

 

Severity  

Cracks: Monitor the crack if it's not too severe, as a split tree can heal itself over a few months with the right care. Gently clean the area, disinfect it, and ensure the tree is well-watered and stress-free to support healing. If the crack is major, contact arborists to save your tree. 

 

Splits: Monitor the split, it will heal itself with proper care. Clean up the area and use Tree Tape or Bandages if needed: However, more significant splits require special attention. For severe splits, a certified arborist can use tactical strategies like cabling and bracing to resolve the problem. 

 

Major Damage? Call an Arborist  

You might be able to save smaller trees from cracks and splits with a DIY approach, but for larger trees, it is recommended to hire a professional tree maintenance company near you. Even for smaller trees, an experienced arborist can treat the damage with reliable assessment and safety.  

 

What Do Arborists Do to Help a Tree? 

Arborists help a tree by performing several key tasks to ensure its health and stability. These include: 

 

  • Bolting: Installing bolts to secure cracked or split limbs prevents further damage and ensures the tree's structural integrity. 

  • Cutting damaged limbs: Pruning or removing limbs that are cracked, split or pose a safety risk. 

  • Stabilizing the tree: Using techniques like cabling or bracing to support weak or leaning trees. 

  • Fertilizing: Applying nutrients to the soil or directly to the tree to promote healthy growth and strengthen its roots.
