Bonsai trees are particularly susceptible to disease and infection after they have just been cut, trimmed or pruned and also when repotting has just occurred. Often general signals that your bonsai tree has been infected are that it will rule to begin to lose its leaves or they will become discoloured and the trees branches may begin to bend and wilt slightly. What is dangerous about infectious diseases such as a fungus or bacterial infection are that once bonsai tree has been infected, the disease can spread onto another tree or plant which is nearby, therefore it is vital and essential that you isolate an infected tree and place it in a secluded location.
The best way to stop diseases is through prevention. This means that you should keep your tree healthy and its environment. Doing this will be able to prevent most of your trees health problems from occurring in the first place. However, there will be times wear you will not be up to prevent infection and it will still occur anyway. In this case you need to keep an eye out for the following diseases.
Leaf spot is the first disease that you should know about. This is where a large number of black, brown or grey spots start forming on the leaves of your tree. This may also occur on any small twigs or branches as well. To prevent this from happening, the best thing to do is to burn off any fallen leaves and fruit which come from your bonsai tree and to remove and burn away any other infected parts of the plant.
