If you suspect that a tree in your garden may be diseased, you will want to know what your next steps will be. It is often hard to determine what steps you will have to take without knowing the exact disease that your tree is suffering from. There are some common tree diseases that could be affecting your tree and you need to know what the signs are. You should also know what steps you have to take once the disease has been confirmed.
Contact An Arborist
In all cases where you believe your tree is diseased, you should contact an arborist. You will need to work with a certified arborist who will be able to inspect the tree and determine whether or not it is diseased. The arborist will also be able to tell you what steps you can take to treat the tree if possible. It is important to note that there are some tree diseases that do not have any treatments or cures and will result in your tree needing to be removed and replaced.
If You Have An Emerald Ash Borer
An emerald ash borer is a green beetle that’s larval stage will damage your tree. This stage will disrupt the tree’s ability to carry nutrients and water to the brands. This green beetle will affect all types of ash trees and can be found in many different states.
If this green beetle is the cause of your tree appearing diseased there is actually nothing that can be done. The tree will need to be removed from the garden and replaced. It is recommended that you not replace the tree with another ash tree as the beetles may return. You will need to hire an arborist so that they can start diagnosing sick trees. The arborist will generally be able to tell you about the best replacement trees that you can use.
If You Have Oak Wilt
As the name suggests, oak wilt affects oak trees and is caused by a soil-based fungus. Beetles will spread the fungus to healthy trees and oak wilt will generally spread through the tree from the roots. This is a very serious disease for oak trees and can kill them in a single growing season. Fortunately, it is possible to control the spread of the disease to other oak trees.
There is no cure or treatment for oak wilt, but it is possible to manage the effects. It is also possible to prevent the disease from spreading to other oak trees in your garden. This can be done by trenching around the oaks as this will reduce the chance of the disease spreading when the roots of the trees touch. The best way to do this will be explained by the arborist as each tree will be different.
If You Have Mountain Pine Beetles
Another common disease that affects various types of western pines is the mountain pine beetle. There are a number of microbes that are spread by the beetle that causes your tree to appear diseased. The problem with this disease is that the signs of infection will not occur until after the beetles have moved to a new tree making it hard to prevent it spreading.
Early detection of this disease is vital if you want to prevent it from spreading. Infested trees will need to be removed from the garden as they can still cause problems. Arborists will generally use pheromone baiting to lure the beetles from the trees and trap them. To prevent this disease, you need to provide trees with enough water and a healthy soil. Stress and drought can cause trees to be more susceptible to an infestation.
If You Have Dutch Elm Disease
Dutch elm disease is actually multiple soil-based fungi that will be exacerbated by elm bark beetles. The beetles will move within the tree and spread the fungus around as it carried it. Contrary to the name, the tree most commonly affected with Dutch elm disease is actually the American elm.
If the disease has been detected in the early stages, it is possible to save the tree. This will be done by pruning the affect limbs of the tree. However, if the disease is not caught early, the tree will need to be removed and replaced. To prevent this disease, it is recommended that you plan hybrid elm trees which have been created to be resistant to the disease.
If You Have Anthracnose
Anthracnose is a tree disease caused by various species of related fungi. The fungi will grow on the twigs and leaves of shade trees such as the sycamore, dogwood, privet, and ash. It is important that you spot this disease early if you want to have a chance at saving the affected tree.
If the disease has been detected early, it is possible to prune the affected twigs and foliage. Once the tree has been pruned, you will need to burn the infected twigs and leaves. However, if you have caught the disease too late and the tree has been overtaken by the fungi, it will need to be removed. To prevent this disease you should ensure that there is good air circulation around the trees that are most susceptible to the fungi thrives in damp conditions.
The first step that you need to take if you think your tree is diseased is to contact a certified arborist. They will be able to confirm the disease and tell you about the next steps that you have to take.
