Trees are living things which can contract different diseases. Each disease has its own specialized cure and only a professional with experience can know about them all. They could be associated with the trunk, the branches, the leaves or the root system. Wherever the disease is, it could be serious and as a layman it would be hard to judge. The survival of the tree depends on the proper identification and cure of these diseases. Proper tree care is required to keep them healthy and live a long life to be able to serve the purpose for which they were planted.
The roots of trees provide sustenance for the tree and if that is diseased then the whole tree is affected. Roots are the most difficult to diagnose if you are a layman as they grow underground and cannot be seen by the naked eye. There are various diseases depending on the type of tree and the kinds of roots that are present. There could be diseases associated with fungus or rot. This by no means is an exhaustive article on root diseases but it touches on how complicated it can be and how a layman would find it difficult to cure.
Even the trunk or branches of trees could have diseases which are hard to identify unless you have the proper knowledge to be able to know them and give the right treatment. The make-up of a tree is in a way comparable to the make-up of a human, whereby each part has a connection to the others and if one part is weak or diseased it could easily stop others from performing at their full potential. Thus if you want to grow a healthy tree you have to make sure that everything is proper and well and at its peak.
Even though the afflictions of the leaves, whether they be related to pests or diseases may be easy to see, they are not easy to identify unless you have the proper knowledge. Tree care is a very important thing and cannot be left to chance, adding many more years of life to your tree are a goal all of us would strive for. Trees serve such an important role in our lives that it is important for us to make sure they have a healthy life too. The last thing anyone would want to do is tree removal.
