A diseased tree is never a pretty sight, nor is it a good sign. In many cases, tree diseases go unnoticed, but it is important to be vigilant and aware of when your tree is showing signs of disease so that you can address the problem promptly before it worsens.
Here at Treespecs, we have compiled a list of the 5 common signs of tree disease that any gardener needs to know.
Let’s take a look at them below…
1. Pests
If you notice that pests, whether that is insects or worms, have infested your tree, then it is likely that your tree is diseased. In particular, beetles and wasps are known to cause tree disease by infecting the bark and laying eggs in the branches.
2. Discoloured Leaves
Never ignore discoloured leaves—spots or mottling can indicate that your tree is diseased, likely suffering from a lack of nutrients. A tree that is changing colour (and not with the season) is potentially dying and requires examination by a professional arborist (like one from Treespecs!). Discoloured leaves can mean that your tree is not getting enough water, sun, or nutrients to photosynthesize.
3. Less Foliage
Trees should have foliage throughout the year (except during winter), especially in the spring and summer. If your tree has reduced foliage or no foliage at all compared to other trees, this could mean that there is a problem. While it is normal for leaves to fall, your branches should not be completely bare and/or have dead leaves attached.
4. Bacteria and Fungi Infestation
Fungal disease is a telltale sign that your tree needs help—you can spot bacteria and fungi infestations from their distinctive white substance when bark is removed. Mushrooms may also form on the tree itself.
5. Cracks on Trunk
Cracks or splits on the trunk, particularly if deeper than the bark, may signal that the tree is unhealthy and possibly compromised in terms of its structural integrity. These types of trees are dangerous and may require swift removal to prevent the tree from potentially falling over.
