Treatment Of Diseases Of Trees And Shrubs


There are a vast multitude of diseases that can effect trees and shrubs, which can either detract from their overall health or kill them. However there are methods in which you can undertake to heal/improve infected trees and shrubs.


Chestnut blight is a tree/shrub disease caused by a fungus that is spread via wind, rain and animals. Once it has come in contact with the tree this disease enters it through the cracks or wounds on the trees trunk, multiplies, creates cankers and effectively kills everything that is located above the developed canker. There is unfortunately no cure for this tree/shrub disease, but to prevent it from spreading to uninfected trees it should be removed from the area without delay.

Oak wilt is is a fungal disease caused by Ceratocystis fagacearum. This diseases of trees and shrubs usually manifests in the Spring time and the red oak tree is especially susceptible to this strand of disease. The affected tree will develop leaves that are bronze color and they will eventually all fall off the tree, discoloration of the vascular tissues, and brown streaks and spots under the bark of the tree. To effectively prevent/manage this sort of tree disease, you should make sure your tree does not develop any wounds/injury in the Spring months, and if a wound does manifest make sure to cover it with tree paint. Another important step to undertake is to regularly prune your trees. Because there is no cure for this diseases of trees and shrubs prevention is the key factor in inhabiting your trees from contracting this unpleasant disease. 


Plant rust is a easily recognized plant disease via its palpable rust color that develops on the tree/shrubs growth. This rust will begin as small flecks but will later develop into prominent bumps that encompass the whole underside of the leaves. The best course of action to undertake in relation to this tree disease is to prevent it from occurring in the first place. This can be achieved by establishing the correct sort of environment for your tree/shrub. This includes not an overly wet area, so do not over water your tree/shrub, and make sure there is good air circulation around your plants. However if your plant does manage to contract rust, remove the affected leaves and dispose of them in a suitable manner. After this treat your entire tree/shrub with a good fungicide.

Little Leaf disease is caused by the  fungus Phytophthora cinnamomi. This variant of disease flourishes in moist and warm conditions. The first signs of an infected tree/shrub will be a slight yellowing and shortening of the needles and reduction of shoot growth. As the disease progresses the diameter of the tree will shrink, and the crown of the tree will become thin and tufted. To help reduce the spread of the fungi disease the breaking up of clay soil around the trees is recommended, as this will establish better drainage, which will subsequently reduce the likelihood of this disease developing.

Tips and comments

The best strategy for the majority of tree/shrub diseases is to prevent them from occurring in the first place. This is due to the fact that once some of these diseases have manifested there is no cure and the tree will have to be destroyed.
