Reasons Your Tree Trunk Is Turning Black

Tree trunks typically turn black when the tree has a disease or an insect infestation. Identifying the exact disease or infestation will depend on the tree’s species and its symptoms. 

For instance, Steganosporium Ovatum is a fungal infection that can affect the tree. It causes black structures to form, which then merge to create a solid black layer on the tree’s trunk. Tree removal is the quickest way to resolve the situation and prevent the disease from spreading to neighboring trees.

But before chopping down your tree, there are a few measures you might want to consider trying.

How to Prevent Your Tree’s Death

You’ve probably spent years caring for your tree, so noticing its trunk blackening can be disheartening. However, not all hope is lost. Though the measures you implement will vary according to the disease, you can save the tree from dying.

Here are a few common tree diseases that could turn your trunk black, along with what you can do to address them.

Gloomy Scale

Gloomy scale is an insect infestation that also causes branch dieback, bumpy textures, and a thinning canopy. Experts will try applying horticultural oils during your tree’s dormant months. Spraying the tree with insecticides in early spring can also help.

Sooty Mold

Why is my tree trunk black? Well, are there plenty of insects feeding on your trees? Sometimes, as they feed, they leave behind excretions. 

However, these insect excretions aren’t harmless; they provide the perfect conditions for sooty mold to grow. Fortunately, horticultural oil sprays and non-toxic insecticides can help you address this issue fast.

Verticillium Wilt

Verticillium wilt is a rather deadly fungus. It grows on the tree’s branches and leaves but also forms black streaks on its trunk. Your tree’s leaves could develop brown spots around the margin. Sudden wilting is also quite common.

Dealing with wilt requires pruning the affected branches, which arborists recommend that you burn or bury the branches you cut.

Bacterial Cankers

This bacteria arises as a secondary infection that targets already weakened trees. It causes the growth of black pustules, which eventually form black layers on the trunk. Besides pruning, spraying the tree with non-toxic fungicides might also help.

Why Reach Out to Tree Experts?

While the above measures may give your tree a fighting chance, it’s best to consult a professional to assess the tree and determine the condition’s severity. If the situation is salvageable, they will be able to implement reliable solutions that will nurture your tree back to its full health. If not, they will provide the removal services you need.
