Learn About Tree Diseases Affecting Your Trees

Weeds, fungi and other tree diseases are a common problem that many people face. Whether you are a landscaper, homeowner or just someone who enjoys the look of a healthy tree, prevention is the key to keeping your trees healthy and disease free. A healthy tree will remain long after other pests have been taken out of the picture. It will survive other common pest attacks such as bark beetles, disease, insects, rot and even fire. The way to keep a tree healthy is to take preventive measures so that if a problem does arise it can be dealt with easily. In this article I will look at some of the best ways to protect your trees from various types of garden pests and disease.

There are many types of diseases that affect your trees. Some are airborne, some are ground-dwelling and some are below the ground. A tree disease can kill your tree in a matter of days and you need to act fast to prevent the problem from becoming a serious threat to your trees or your garden. Prevention is better than cure and by taking preventative measures you can keep your trees healthy for longer.

 

Most of the tree diseases that affect trees can be identified by the symptoms that appear. If you see leaf discoloration, brown patches or bald spots on the leaves then you have a tree disease. You will also notice that the roots are wilted and may even break as a result of the disease.

 

One of the most common diseases is needle blight that affects young trees. There are several forms of fungi that attack young trees and it can spread quite rapidly to other nearby trees. As the name suggests, it results in the killing or weakening of the needles and can spread to the whole tree. There is also what is called ‘snow blight’ which is quite similar but occurs on the needles and branches of young trees and not on the roots. These two diseases can both be treated with fungicides.

 

Black spot, otherwise known as ‘ring blight’, is a tree disease that is caused by the fungi named dermatophytes. This fungi penetrate the bark of the tree and starts feeding on the cells of the bark. As it feeds, the fungus releases spores which will grow into root systems and create problems for the tree. In most cases, the affected trees must be removed as the disease spreads throughout the tree. The affected trees do not recover from the disease and die after a few years.

 

Another common tree disease is white spot. It is often confused with ring blight but is actually a different type of fungi. As the name suggests, white spots appear on the tree bark where the fungi have caused a wound. Again, this is a very serious condition and treatment should be done immediately if you see any white spots on the bark of the tree. However, the fungi do not infect the leaves, branches or twigs.

 

Tree diseases can affect both young and old trees. If it is serious, you should isolate the infected part of the tree and cut off its limbs or trunk to stop the spread of the fungi. You should also clean the area thoroughly with insecticide to prevent the fungi from spreading to other parts of the tree. The fungi also reproduce faster in a humid or moist place so treating the tree right away is very important.

 

Other tree diseases affecting the whole tree can include needle blight, scale, root rot and root knot. If fungi are the cause of the disease, the affected part of the tree would die when the treatment is started. As for scale, the entire tree would lose its scale (the exposed bark, twigs and leaves). As for root rot, the affected portion of the tree would succumb to the disease. Tree diseases affect the health of the tree and can affect its production and fruit yield. To prevent tree diseases affecting your trees, you should regularly inspect your trees for signs of disease.
