Are your trees under attack? From withering leaves to mysterious fungi, in this article we will explain how to spot signs of tree disease.
The health of trees is crucial for maintaining the beauty of our surroundings, as well as encouraging wildlife and the local ecosystem. In public spaces or business premises, the condition of trees is also an important safety factor.
Unfortunately, trees are susceptible to various diseases that can compromise their wellbeing and even lead to their demise. As trusted local tree surgeons, Branching Out aims to raise awareness around tree diseases to empower individuals with the knowledge to identify and address potential issues.
In this article, we will explore how to spot signs of tree disease, enabling you to take proactive measures to protect your environment.
Make a visual inspection
The first step in identifying diseases is to conduct a visual inspection of the tree. Take note of any noticeable changes in the tree’s appearance, such as discoloured or wilting leaves. Yellow or brown leaves, especially during the growing season, can be an indication of disease.
Other visual clues include dark spots, irregular patterns or lesions on the leaves, which may indicate fungal or bacterial infections. Next, check for dead or damaged branches that are brittle or have missing bark. These could pose a safety risk and should be addressed promptly.
Finally, sunken areas on the trunk or branches (known as cankers) and peeling or cracked bark, can indicate disease or pest infestations.
Monitor growth patterns
Observing changes in the growth patterns of a tree can provide valuable insights into its health. Look for signs of stunted or sparse growth, such as reduced foliage or a significant decline in the tree’s overall size. Try comparing the tree’s growth to nearby healthy specimens to identify anomalies.
The emergence of small shoots or suckers at the base of the tree or along its branches can indicate stress or disease. These growths are often a tree’s attempt to compensate for a weakened state.
Check for pest infestation
Trees affected by disease are more vulnerable to pest infestations. Keep an eye out for pest-related damage such as small holes in the trunk or branches, accompanied by sawdust residue. These are signs of wood-boring insects like beetles.
Other insects are easier to spot, including aphids, caterpillars and ants. Check the undersides of leaves and tree crevices for signs of insect activity.
Fungal growth
Fungi can often be observed on trees suffering from disease. Look for mushrooms or conks growing on the trunk, roots or surrounding soil – this can indicate the presence of rot or decay within the tree. Discolouration of the bark, such as dark streaks or black patches, can be a result of fungal activity, so pay attention to any changes.
