Fruit Tree Disease & How To Prevent It
Including a fruit tree or two in your garden design can add a great deal of interest and beauty. Even in the smallest garden it is possible to buy small fruit trees or fruit trees that have been cleverly grafted together onto rootstock that ensures that it remains a manageable size.
Some can even be grown in containers, which can be extremely useful, for gardens in areas wish have a cooler climate, as it means that a tree can be moved into a greenhouse during the winter months. If you choose to grow a type of fruit tree that bears pitted fruit (cherry, plums and the likes) you will need to learn a little about how to avoid disease as these trees can prove a little more susceptible than other types.
A sadly common fruit tree disease is Brown Rot which is a fungus that appears on fruit. Usually it develops on fruit that has fallen from the tree and been left to rot. As Brown Rot is a fungus it can spread very quickly as fungus produce lots of tiny little spores which, due to their size, are highly mobile.
Fungus grows best in damp areas that do not have good air flow. The spores of fungus land on the area and quickly establish themselves and start producing more spores in a very short space of time. One of the best ways to protect your fruit tree from fungal infection is to prune it carefully.
A good strong and healthy tree with vigorous growth will be more able to avoid infection, or, if it does develop disease it will be well equipped to recover from it quickly. One of the ways in which we can ensure that our trees remain in peak condition is to prune them regularly. Pruning trees is vital to their well being in many ways and, in the case of fungal diseases, pruning helps to increase air flow through the branches thus minimizing the number of places which would be suitable for fungus to establish itself.
As well as pruning to improve air flow it is important to prune any areas that show symptoms of fungal infection. Place any clippings in the bin or burn them immediately. Do not allow any infected material anywhere near your fruit tree and pick up any fallen fruit regularly so that it does not stand a chance of becoming infected.
Another fungal disease that can appear on a fruit tree is cytospora canker. Cytospora canker shows itself as dark patches of soft material on the branches of a tree. A large callus can form from which a substance, looking somewhat similar to gum, oozes from the bark. Usually cytospora canker appears close to or right on an old wound a it is during the healing process that it becomes infected by the pathogen.
Again, to avoid this fungal infection/disease it is necessary to prune your fruit tree correctly. Great care should be taken to ensure a clean cut that will heal quickly and stand little chance of becoming infected with cytospora canker or any other fungus.
The two fungal diseases mentioned above, Brown Rot and cytospora canker, are but two of a number of different diseases which can infect a fruit tree. Fungal infections can be very problematic and even professional landscape gardeners can find themselves in some difficulty when trying to combat such a disease. Of course providing the correct amounts of water, sunlight and nutrients can greatly help a tree to grow healthy and strong. However, if you want to ensure a good annual crop from fruit trees you should really invest some time into finding out more about tree care and disease.
