Unhealthy Tree Symptoms

Here are symptoms to keep an eye out for:

The top of the tree withering

Furthest from the life giving roots, the top of the tree is often one of the first sections to suffer.

Discolouration of leaves

It may not only be a sign of autumn, it may be one of the first signs that you will need North Sydney tree removal. Lighter than usual shades, yellowing or browning leaves may indicate poor tree health.

Foliage wilting

Some common signs of sickness include spots, postules or insects on leaves, or holes in leaves.

Varying foliage density

A healthy tree generally has a fairly even covering of foliage. If there is less concentration in some areas of the tree, particularly at the crown, it may be at risk.

Sap on the bark

Sap acts as a defense mechanism for trees, so its presence may be an indication that your tree is suffering in some way.

Abnormal growths

Look out for unusual growths on the trunk, branches or twigs of your tree. This can be an outward sign of disease.


The presence of some insects is expected in the natural environment, but if there seems to be excess in your tree, this may be a sign that it has been infested. Termites are a particularly prevalent reason for tree removal on the North Beaches.
