PESTS AND DISEASES: All Bonsai are susceptible to disease and attack by pests. It is important to diagnose the symptoms of a problem correctly so it may be treated with the correct substance. If your not sure of a problem, take the tree to your local garden centre for careful diagnosis. This may save you much heartache and money, which may be the result of trial and error guesswork with a bonsai problem.

Be careful not to confuse over watering for a disease of some sort. The leaves on trees that are over watered can turn yellow and fall off. Overwatering is nearly always the cause of drastic off- seasonal leaf fall .
