Below are some of the common problems and diseases that trees have and how they can be helped.
Problem Type: Disease
Tree Affected: Elm
Dutch Elm is a disease that has affected elm trees severely all through America. It spreads quickly from one elm to another because of the ascomycete microfungi that that the European or American bark beetle carries. It also can go to the other elms that are close by that through the affected tree’s roots. You might notice your tree’s branches starting to wilt and then eventually yellowing from their crowns and then going to the base. The branch will begin turning brown before they dry up.
Because the disease usually starts at the branch’s crown, it’s a good idea that you cut down the parts that are infected. You also might administer therapy through fungicidal injections into your plant. If you catch is quickly enough, your treatment will likely be successful. But you have to catch the disease early.
Problem Type: Blight
Tree Affected: American Chestnut
This problem is caused because of a pathogen known as cryphonectria parasitica. It’s possible you’ll notice spots that are orange in color upon the tree’s trunk and branches. A sunken kind of canker’s formed upon the tree and this could eventually cause the surface of the tree to girdle. Another symptom you might notice are spores that are yellow in color that come from the affected area of the tree when it’s humid.
The best way that you can help with this problem is through a hypovirulence transfer or soil compress. These are procedures that only professionals can do.
Problem Type: Fire Blight
Trees Affected: Fruit trees

Among the disease’s first symptoms is that there is a layer of white powder on the fruits and foliage of the tree. When the infection’s more advanced, the patches begin growing black or grey.
