Maple Tree Diseases



Top 4 Maple Tree Diseases


If you have maple trees that are starting to look battered, it may have caught one of many maple tree diseases. Maple trees are beautiful and can really spice up an otherwise boring yard. These trees can grow up to 145 feet and can be recognized by there leaves. The leaves have a vein pattern to them which makes them easy to spot.  They have seedlings or fruit that are also easy to recognize. The seedlings resemble a snow pea and many children have played with these seedlings, calling them whirly birds. Although they are a hearty type of tree, they are susceptible to getting maple tree diseases.


When a tree is infected with a disease you can easily see it. There will either be spotting on the leaves or the bark may become a different color. The tree might seem like it is dying and the leaves can wither up. It is important to know what maple tree diseases can infect your tree and what to do about them.


Anthracnose is a fungal disease that attacks not only maples but other trees as well. Different strains of this disease pertain to the different types of trees and attack accordingly. Because of increased hot wet weather, trees can become infected during a bud period.  Some of the symptoms include leaves turning a pale yellow color, misshaped twig formations, twigs and leaves being killed off and leaves falling off in abundance, too soon. Although this disease may not kill the tree immediately, the premature falling off of the leaves can make the tree unable to protect itself through the autumn and winter months. Purple spots can also appear on the leaves and throughout the veining area.


Tar spot is another one of the maple tree diseases. It is not as severe as other types of tree illnesses but nevertheless, it does do damage to the leaves. Tar spot starts out by turning the leaves a yellow color. From there small tar like looking patches start to from and spread on the leaf surface. Some leaves may also wither up and fall off the tree prematurely.


Maple wilt or verticillium is one of the most serious and fatal of the maple tree diseases. It is a soil born fungus and can quickly take over and kill a tree. The symptoms of this disease include a green streaked sap and withered and dying leaves. The branches that are infected will be clearly dead and must be removed immediately. If much of the tree is affected by this disease, it will need to be cut down and destroyed. Fallen leaves must also be raked up and burned because this illness can easily spread to other trees. Once this disease takes total control the tree can die within one season. But if it is a hearty, healthy tree it may take several years for it to succumb to this disease.


Sap streak disease is another fatal type illness. It is also associated with a fungus and once a tree becomes infected, it will never recover. The tree will seem normal until you notice that the braches and foliage aren’t growing. After a number of years it dwarfs the whole tree system and a dark brown staining will appear within the bark. Any trees infected with sap streak must be immediately destroyed so that the infection does not spread.


Although many of the diseases that affect maple trees are not fatal, it is sometimes still a good idea to have the problem diagnosed by a tree care professional. In many cases they can spray the tree with an anti fungal medicine or suggest another procedure that might help cure the tree.
