Why a tree health check matters for Norwest properties

A tree health check from a certified arborist shows whether a tree is sound, needs work or poses a risk to your home, fences, driveway and neighbours. Decay, disease and structural weakness often start out of sight, in the soil, the roots or the upper crown. By the time they show in the leaves, the damage is usually well advanced.

Arborists recommend a yearly inspection so problems are caught while there are still simple options, such as targeted pruning or treatment. Waiting until a tree is visibly struggling tends to narrow those options.

Species and soil change the picture. Some trees have shallow roots and are more likely to uproot in gusty winds, while fungal diseases often begin in the soil around the trunk. That is why each tree is assessed case by case rather than against a generic checklist.

Checks are worth repeating more often as storm season approaches. Roots, trunk integrity and canopy health all affect how a tree copes with strong wind. If a tree turns out to be unsafe, council permit guidance is part of the process before any tree removal service is planned, and the written findings record the tree’s condition before removal.

What a tree health check includes

Trunk flare and bark

The arborist starts at the base. The trunk flare should be visible and widen gradually into the roots. A buried flare can point to planting depth problems or soil build-up that leads to decay.

Bark gets a close look too: loose or missing patches, vertical cracks, fungal growth, swelling, insect activity and bore holes all tell part of the story.

Crown, deadwood and past pruning

The crown shows overall vigour. The arborist checks canopy density, leaf colour, lopsided growth, crossed branches that rub, and unusual leaf drop.

Deadwood is measured, and old pruning wounds are checked for how well they have healed. Odd healing patterns and a thin canopy often signal a tree in decline.

A tree can look fine from the lawn and still be hollow at the base. That’s why we check the trunk and soil, not just the leaves.

Soil and roots

Many fungal diseases start in the soil, so the ground around the tree is inspected for dryness, compaction and signs of root damage.

Can I check my tree's health myself?

A simple self-check you can do at home

A quick walk around the tree is a sensible first step. Look at the trunk, check the ground for fallen bark or branches, and note the colour and condition of the leaves.

Warning signs worth noting

  • A leaning trunk, which can point to decay or infestation
  • Deep cracks in the trunk
  • Brittle bark that sheds often
  • Dry soil around the base, suggesting less water is reaching the tree
  • Fungal growth, unusual swelling or bore holes

When to call an arborist instead

A self-check only covers what you can see from the ground. Hidden decay, weak branch unions and root problems need an arborist inspection by someone with the training to judge the risk of failure.

Trees Down Under offers a free tree inspection across Norwest and the Hills District. Same-day quoting is available where the schedule allows, and the findings come in writing, so you can decide with the facts in hand.

How does a professional assessment differ from a quick look?

An arborist inspection goes well beyond a walk around the tree. AQF Level 3-5 certified arborists use specialised tools and techniques to examine hard-to-reach areas and spot risks the untrained eye can miss. They judge health and vigour from canopy density, deadwood and how past pruning cuts have healed, and they factor in species.

The result is a clear read on the likelihood of branch or tree failure. Where a tree is unwell, the arborist can diagnose the problem and recommend specific treatment, so the next step is based on written findings rather than guesswork.
