Tree Surgery – Looking Out for Diseased Trees

Tree diseases may not sound the most pressing of issues, and to the layman might even sound vaguely comical and bizarre, but to anyone who takes pride in their garden trees it can be a major worry. Tree farms, used to create and harvest lumber responsibly have been devastated by particularly bad blights and diseases, with millions of pounds of quality wood and trees having been lost through inattentive farm maintenance, and the same thing can happen (albeit on a much smaller scale!) in your garden. Tree diseases can very quickly sweep through areas, infecting and quickly killing large numbers of tree. However, if you know the signs, and catch the diseases and blights early on, then you can expect to save the precious tree, and prevent the further spread of the disease. Here’s some key things to look out for.

Study the Leaves

Study the quality of your trees leaves. Leaf growth and healthiness can be a great indicator of a trees overall health, and if you’re noticing vast patches of missing, discoloured, or patch leaves, then your tree may be suffering from a tree disease or blight. The key points to look out for are discoloration, where vast swathes of the leaves can turn yellows and browns, in localised groups. This can also be indicative of limb death, but if it’s widespread it can indicate overall tree disease. Another huge point is leaf loss and patchiness. When at tree enters winter it loses all its leaves at a steady rate all over. An unhealthy tree might start losing leaves all year round, and it could lose them in localised patches, leaving you with a patchy, and exposed looking tree.


Strange looking growths in the bark of a tree can also indicate sickness. Study the bark, limbs and trunk of your tree for unusual lumps, shapes and formations. This can indicate a wide variety of illnesses, sicknesses and mutations. Trees can get cancer just like humans, and this can leave them vulnerable to variety of illnesses and blights. Studying your trees, and knowing how they’re faring is important to keeping them healthy and happy.

Dead or Dying Limbs

Very often, you’ll see tree with parts of their branch structure dying or dead. This can be a sign of sickness and disease, but is more often due to breakages in the structure due to wind or general weakness. Overgrown ivy can lead to this too, as it deprives the tree of crucial light and nutrients. Any ivy growths should be dealt with as quickly and effectively as possible, and always before it can grow and spread to other trees.

What You Should Do

Once you’ve identified tree disease or blight, the very first thing you should do is bring in the experts. Drafting in skilled, expert tree surgeons, who understand how to manage and care for trees is the quickest and best way of healing your sick trees, and should be done as quickly as possible, to increase the chances of the tree surviving, and preventing the disease spreading.
