5 Signs Your Tree Needs to Come Down

One of the most common questions we hear is: "I think my tree might be a problem — but is it actually dangerous?" It's a fair question. Trees are long-lived, and many that look rough are actually structurally sound. But some are genuinely hazardous — and in Adelaide's suburban environment, a tree failure can have serious consequences.

Here are the five signs we look for when assessing whether a tree needs to come down.

1. A Significant Lean — Especially a Developing One

Some lean in trees is normal and has been there for decades. What matters is whether the lean has developed — if a tree that was previously upright has started to tilt, that's a warning sign of root failure or structural compromise that warrants immediate professional assessment.

Also look at what the tree is leaning toward. A tree with a longstanding gentle lean away from structures is low-risk. A tree leaning toward the house, a fence, or a neighbour's property is a different matter entirely.

2. Dead or Hanging Branches in the Crown

Deadwood is a normal part of tree ageing — even healthy trees shed branches over time. But a significant volume of dead branches in the canopy, or large hanging limbs caught in other branches ("widow makers"), are a genuine hazard. Dead branches dry out, become brittle, and can fall without warning — particularly in wind or after rain adds weight.

Look for:

• Branches with no leaves during the growing season (when surrounding branches have foliage)
• Bark-free sections of branch
• Branches resting in the forks of other branches
• Fungal growth on upper branches (often indicates internal rot)

Significant deadwood doesn't necessarily mean the whole tree needs to come down — targeted deadwood removal and pruning is often the right answer.

3. Fungal Growth at the Base or on the Trunk

Bracket fungi, mushrooms, or shelf fungi growing from the base of the trunk or from major roots are a serious warning sign. These indicate internal decay — the tree may appear healthy from the outside while being significantly compromised structurally inside.

The presence of fungi doesn't always mean immediate removal is required, but it does mean a professional assessment is — the visible fungal growth is just the surface expression of decay that may extend much deeper into the wood.

4. Major Cracks or Splits in the Trunk

Shallow vertical cracks in bark are usually normal. Deep splits, horizontal cracks, or splits that extend through the trunk are not. Co-dominant stems (where a tree has split into two main trunks) are a known failure point — if there's a tight V-shaped union between two major stems rather than a flared U-shape, there's often bark inclusion at the join, which is a weak point that can fail under load.

After storm events in Adelaide, it's worth checking your trees for new cracks that may have developed under wind stress — a crack that opened slightly under load might close again after the wind drops, but the structural damage remains.

5. The Tree Is Dead or Dying

A dead tree needs to come down — the question is timing. A dead tree standing in a suburban yard becomes increasingly hazardous as wood dries out and root decay progresses. The structural integrity of a dead tree degrades over months to years depending on species, position, and weather.

Signs a tree is dead or in terminal decline:

• No leaf growth in spring (for deciduous trees) or brown/no foliage on an evergreen
• Bark peeling away from the entire trunk
• Roots visibly dead or decaying
• Wood is brittle, crumbling, or hollow when probed

If you're not sure whether a tree is dead or just stressed, have it assessed before making a removal decision — some trees recover from severe stress, drought, or pest damage if given time and appropriate care.

What to Do If You're Concerned

If your tree shows one or more of these signs, the right step is a professional on-site assessment. We'll look at the whole picture — species, position, structural integrity, proximity to structures, and root zone condition — and give you an honest opinion on whether removal is necessary, whether targeted work (pruning, deadwood removal, cabling) would manage the risk adequately, or whether the tree can simply be monitored.

We don't recommend removal when it isn't needed. Healthy trees add value to Adelaide properties — good canopy is worth keeping where it's safe to do so.
