Trees can fall victim to all sorts of infections and infestations. A tree trunk can slowly turn black until one day you notice and wonder, “why is my tree trunk turning black?” There are several causes for a tree trunk turning black.
When you need professional tree service in Wake Forest including figuring out why your tree trunk turned black, Raleigh Tree Service is available to inspect the tree and determine the cause.
Gloomy Scale
Gloomy scale is an insect infestation that is completely preventable by applying insecticide in the spring while insects are dormant. It commonly appears in the southeastern United States, where the climate is warm and humid. Signs of gloomy scale include a thinning canopy and a lot of branches dying off in addition to a black tree trunk.
If you notice gloomy scale when the infestation is still small, you can use a pressure washer to wash away the insects before they start to affect the tree.
Sooty Mold
Sooty mold forms on excrement left behind by insects as they eat trees. It occurs all over the United States, most commonly on Elm and Maple trees. The trunk may turn black, as well as the leaves and branches. Insecticides can make the trees an unpleasant place to infest, and they will leave, improving your tree health.
If you have a chronic problem with sooty mold, you may ask yourself, “why is my tree trunk turning black?” Pressure washing the infected trees once per week will keep insects out and can restore the natural color of your tree.
Bacterial Cankers
This fungal infection is just as nasty as it sounds. It most commonly plagues Northern regions, but it can pop up in other areas. Bacterial cankers form on trees that are already in poor health. Black barnacles form on the tree and blanket the branches and trunk with black ooze.
Because bacterial cankers don’t form on healthy trees, by the time you notice them, you could have a big problem on your hands. The best way to prevent them completely is to schedule regular service with a professional arborist and keep your trees in good health.
If you notice bacterial cankers before they cause too much damage, you can try to save the tree. The best-case scenario is that the cankers formed far enough out for you to cut them off and leave at least eight inches of branch on the tree.
Don’t leave any cankers on your property to spread. Remove them or burn them to make sure the infection is totally eradicated.
Maintaining Tree Health
There are a few things you can do to prevent fungal infections and bacteria growth that lead to tree disease. Pay close attention to your trees. If you notice signs of decay or disease, prune off the affected branches right away to prevent spreading.
Maintain the soil so it is in good condition. In areas with high levels of moisture, fungus can quickly overtake your trees.
Survey the soil around your trees for signs of larvae that could grow into insects that destroy your trees.
When To Schedule Professional Tree Removal
If a diseased tree reaches the point where it cannot survive, the safest option is to call a professional for removal. If a rotting tree falls on your property, it could fall on your home, your car, or a person. Tree disease could spread to other areas of your property.
