Dealing With Split or Cracked Trees: Expert Tree Care Advice

January 24, 2026

Split or cracked trees are a common concern for property owners, especially after storms, prolonged wet weather, or periods of drought followed by heavy rain. While a damaged tree may still appear stable, internal weaknesses can develop silently, creating potential safety risks to people, buildings, and surrounding land. Understanding why trees split, how serious the damage may be, and what steps to take next is essential for protecting both your property and the tree itself.


This guide has been written to help homeowners and landowners make informed decisions when dealing with split or cracked trees.


Why Trees Split or Crack

Trees can split or crack for a variety of reasons, and the cause often determines how serious the damage is. One of the most common triggers is sudden stress placed on the tree’s structure. High winds can cause heavy branches to sway, creating pressure at weak junctions or along the trunk. If the internal wood fibers cannot cope with this movement, cracking may occur.


Rapid changes in moisture levels also play a significant role. During dry periods, wood can shrink slightly, and when heavy rainfall follows, the sudden expansion can cause stress fractures, particularly in older or already weakened trees. Frost damage is another factor, as freezing temperatures cause moisture within the wood to expand, leading to internal cracking that may only become visible later.


Poor tree structure is another common contributor. Trees with co-dominant stems, where two main trunks grow closely together, are more likely to split as they mature. Included bark between these stems prevents strong wood-to-wood bonding, making the tree more vulnerable under load. In such cases, professional intervention from a tree surgeon is often required to determine whether the tree can be stabilized or if removal is the safest option.


Assessing the Severity of a Split or Crack

Determining whether a split or cracked tree is genuinely unsafe requires professional judgement. While some damage may be cosmetic, other signs can indicate deeper structural problems, which is why many property owners begin by searching for a tree surgeon near me to obtain a clear and reliable assessment.


  • Surface cracks may appear severe but can be superficial, while smaller openings may suggest internal decay.
  • The depth, length, and position of the split are key factors in assessing overall risk.
  • Cracks affecting the main trunk or major structural limbs are more concerning than those on minor branches.
  • Splits that widen during windy conditions or show visible movement indicate a higher likelihood of failure.
  • The presence of fungal growth, cavities, or soft wood around the damaged area can signal decay and reduced strength.
  • A professional inspection prioritizes safety by considering nearby buildings, footpaths, roads, and neighboring properties while aiming to preserve the tree wherever possible.


Management and Treatment Options

Once the severity of the damage has been assessed, several management options may be considered depending on the tree’s overall condition. In some situations, selective pruning can reduce excess weight on affected areas, easing strain on the split section and helping to lower the risk of further damage. This approach is often suitable when the crack is minor and the tree remains structurally sound, and it can also be a more cost-effective solution, as tree surgeon costs are generally lower for targeted pruning than for more extensive work.


For trees with structural weaknesses but significant landscape or ecological value, bracing or cabling may be considered. These systems provide additional support by limiting movement between limbs or stems, allowing the tree to continue growing while reducing the likelihood of failure. This option requires careful design and ongoing monitoring to remain effective.


In more severe cases, partial dismantling or complete removal may be necessary. This is usually recommended when the split compromises the tree’s stability or poses a clear danger to people or property. Many people researching tree surgeons in my area are understandably concerned about disruption, but professional removal is carried out in controlled stages to minimize impact on the surrounding environment.


Discussions around tree surgeon prices often arise at this stage. Costs can vary depending on the size of the tree, access restrictions, and the complexity of the work involved. Transparent explanations of what the work involves and why certain methods are recommended help clients feel confident in their decision-making process.


Preventing Future Tree Damage

While not all tree damage can be prevented, proactive care significantly reduces the risk of splitting or cracking. Regular inspections help identify structural weaknesses early, particularly in mature trees or those close to buildings. Addressing issues such as poor branch unions or unbalanced canopies before they become critical can extend a tree’s lifespan and improve safety.


Appropriate pruning is one of the most effective preventative measures. Removing excessive weight from overextended limbs reduces stress during high winds and heavy snow. Good pruning practices also promote balanced growth, which helps distribute forces more evenly throughout the tree.


Soil health and root care are often overlooked but play a vital role in overall stability. Compacted soil, poor drainage, or root damage from construction work can weaken a tree’s anchorage, making it more susceptible to splitting. Professional advice ensures that both above-ground and below-ground factors are considered as part of a long-term tree management plan, often guided by a qualified tree surgeon.
