Trees are a valuable part of your property, offering shade, beauty, and even increasing the value of your home or commercial space. But just like any living thing, trees can become sick. Tree disease is more common than many realise, and spotting the early signs is key to preserving the health and safety of your outdoor spaces. At Yorkshire Tree Surgery, we believe that prevention is better (and cheaper) than cure. Here’s how you can identify the warning signs of a sick tree and when to call in expert tree care solutions to avoid potential hazards or unnecessary diseased tree removal.
Discoloured or spotty leaves
Leaves should be vibrant and full of life, especially during the growing season. If you notice:
Yellowing or browning of leaves out of season
Black, white or brown spots
Curling or wilting
…it could be an early sign of a fungal or bacterial infection. Catching this early can allow for treatment rather than removal.
Unusual growths or fungus
Mushrooms growing at the base of a tree or on the trunk may look harmless, but they can signal internal rot. Other growths like cankers (sunken, dead patches on bark) also indicate disease and decay.
Fungal infections in particular can spread quickly, harming not just one tree, but neighbouring ones too.
Dead or falling branches
A healthy tree regularly sheds smaller twigs, but large or frequent branch drops are concerning. If branches appear brittle, dry or lifeless, this could point to root rot or internal damage. Not only is this a disease indicator, but it’s also a safety risk, especially near buildings or footpaths.
Peeling or cracked bark
The bark is your tree’s first line of defence. When it starts to crack, peel excessively or fall away in chunks, it's often a sign the tree is struggling. Bark damage can result from insect infestations, fungal infections or environmental stress.
Visible pests or holes
Insects like aphids, beetles or caterpillars can do serious damage, and so can the diseases they carry. Small holes in the bark or signs of boring insects should never be ignored. If left untreated, infestations can weaken the tree and invite further infection.
Slow or stunted growth
If your tree isn’t growing as expected or appears smaller and weaker compared to others, it might be suffering from disease, root issues or nutrient deficiencies. A professional assessment can determine whether it’s something treatable or a deeper problem.
Why early action matters
The earlier you catch signs of tree disease, the more likely you are to save the tree. In many cases, professional pruning, targeted treatments or soil care can revive a sick tree and save you from the cost and hassle of diseased tree removal later on.
