How Do You Tell if a Tree Has a Disease?

What to Look Out For

Trees are susceptible to all kinds of diseases, and left untreated these can weaken or even kill them. That’s why recognising the early signs of disease is so important! As one of the leading providers of tree surveys Woodbridge has to offer, we’re here to tell you what to look out for!

Abnormal Leaf Colouring and Wilting

One of the earliest and most visible signs of a diseased tree is the condition of its leaves. If you notice yellowing or browning leaves, this could be a sign of a fungal or bacterial infection. Keep in mind that some discolouration can be due to seasonal changes, so be aware of the time of year. Leaves that wilt despite proper watering may point to root or vascular diseases.

Dead or Dying Branches

A healthy tree should have strong branches. If you notice any branches that are brittle or dying, the tree could be suffering from diseases such as dieback or canker, as these can cause branches to die prematurely. Another thing to look for is the branch bark beginning to peel away, or if cracks appear along the branches.

Unusual Growths on the Bark

The tree’s bark often reveals the first signs of any issues. Fungal infections can cause noticeable growths on the bark, such as mushrooms or conks. Any oozing sap or dark streaks running down the bark should be treated with urgency too, as they can be a sign of a bacterial infection or insect infestation.

Spots and Blotches on Leaves

Fungal or bacterial diseases can cause spots or blotches on the surface of the leaves. These may begin to spread, leading to premature leaf drop. If you notice clusters of small spots in an irregular pattern, it’s time to give us a call! Some trees can recover from mild infections, but severe or repeated outbreaks may weaken the tree’s overall health.

Root Damage and Fungus

Although tree roots are often hidden from sight, certain things will tell you how healthy they are. Trees with diseased roots may show symptoms such as stunted growth, sparse foliage, or leaning. Root rot is a common issue, and it can be fatal if not treated promptly. You may also notice fungal growth at the base of the tree. This can spread underground, affecting the roots of nearby trees too.

Cracks or Cankers on the Trunk

Deep cracks or sunken areas on the trunk that are known as cankers are often signs of disease. Over time, they can weaken the structural integrity of the tree, making it more vulnerable to breakage. These areas of damage provide an entry point for things such as further infection, insects, or even wildlife, adding to the tree’s issues.
