A leaning trunk, peeling bark, or fungus at the base are not just cosmetic issues. They are often the early warning signs of a tree that is quietly becoming a safety risk to your home, your family, or the property next door.
In Melbourne, where wild winter storms and dry summer heat regularly test even the healthiest trees, knowing what to look for can be the difference between a planned removal and an emergency callout at 2am. Here are the five warning signs every homeowner should know.
Why early detection matters
Trees rarely fail without warning. The signs are usually there for weeks or months before a branch comes down or a trunk splits. The problem is most homeowners do not know what they are looking at until it is too late.
Spotting problems early gives you options. You can schedule routine work in winter (the cheapest and safest season for removal), apply for any required council permits without time pressure, and avoid the premium that comes with emergency callouts.
1. The tree is leaning, or the roots are lifting
A new lean is one of the clearest danger signs in any tree. Some trees grow with a natural lean over many years and remain perfectly stable. The real problem is a sudden lean, or one that gets worse after a storm.
Look for:
- Cracked or lifted soil on one side of the trunk
- Roots visibly pulling out of the ground
- A trunk angle that has changed in the last few months
- The tree leaning toward your house, fence, or power lines
If any of these are present, do not park your car under it, and do not wait for the next windy day. This is the most urgent sign on the list.
2. Dead or dying branches in the canopy
Arborists call them "widow makers" for a reason. Dead branches can break and fall without warning, even on a still, sunny day, and they are heavy enough to cause serious injury or property damage.
Walk around your tree and look up. Watch for:
- Bare branches mixed in with healthy foliage
- Limbs with dry, brittle, or peeling bark
- Sections of the canopy that did not leaf up in spring
- Visible fungus or mushrooms growing from a branch
A few small dead twigs are normal. Large dead branches, or more than 25% of the canopy looking unhealthy, mean it is time to call a qualified arborist.
3. Cracks, splits, or hollow sections in the trunk
The trunk is the structural spine of the tree. Any visible damage there is a serious red flag.
Inspect the trunk for:
- Vertical cracks running up the bark
- Splits where two trunks meet (especially V shaped junctions)
- Hollow sections that sound dull when tapped with a stick
- Bark falling off in large patches and not regrowing
- Visible cavities, holes, or rot
Some hollows are stable for decades. Others are one storm away from snapping the tree in half. Only a qualified arborist can tell the difference, and the assessment is usually free as part of a quote.
4. Fungal growth at the base or on the trunk
Mushrooms or bracket shaped fungi growing on a tree are not a good sign. They are often the visible symptom of internal decay that has been progressing for years.
Common Melbourne offenders include armillaria root rot and various bracket fungi that quietly hollow out the trunk. By the time fruiting bodies appear, the structural damage is usually advanced.
Do not try to remove the fungus yourself. It is a symptom, not the problem. Get the tree assessed by a qualified arborist to determine how much wood is still sound.
5. Pest infestation or borer damage
Australian native trees, particularly eucalypts, are susceptible to longicorn borers, termites, and a range of other pests. Look for:
- Small round holes in the bark, sometimes with sawdust beneath
- Mud trails up the trunk (a tell tale termite signature)
- Sudden thinning of the canopy or yellowing leaves out of season
- Bark that lifts away easily and reveals tunnels underneath
Severe infestations weaken the wood from the inside and can leave a tree structurally unsound long before it looks unhealthy from the outside.
What to do if you spot any of these signs
Do not try to assess or remove a damaged tree yourself. Even smaller trees can shift unpredictably once cuts are made. The right move is to get a qualified arborist to inspect it, document the condition with photos, and recommend either pruning, cabling, or full removal.
