Is White Fungus on Trees Dangerous?

When taking care of your trees, you might notice white fungus growing on them. Any unusual growth is cause for concern, and you might find yourself asking, “Is white fungus on trees dangerous?”

The short answer is yes. By the time you see white spots on the plant’s surface, it may have eaten up a substantial portion of the tree from the inside. 

Let’s dive deeper to learn more about this fungal disease, including some preventative measures as advised by a highly sought-after tree removal company in Palm Bay, FL

What Is White Fungus? How to Spot the Infection

You need to first understand what this disease entails to answer the question, “Is white fungus dangerous?”

When you notice white mold on your tree trunks, either heart rot or powdery mildew could be the cause. These two fungal diseases have glaring differences and are quite easy to diagnose and treat. 

What Is Heart Rot? 

Heart rot commonly attacks woody trees, destroying their trunks and branches from the inside out. That means you won’t notice any signs of this fungal infection until it has done substantial damage. 

If your tree bark has a cut, you might be able to tell that it is rotting from the inside. At the advanced stages, you’ll notice some white growth on the trunk. Whitish, mushroom-shaped fruiting bodies, known as brackets or conks, will appear on the outer part of the trunk. 

If you see only one conk, it means that roughly one cubic foot of decayed wood lays behind it. So, several conks on your tree’s trunk translate to severe damage.

What Is Powdery Mildew?

Powdery mildew affects all types and plants, but basswood, maple, magnolia, and dogwood are the most vulnerable tree species. It’s the most common cause of the white stuff growing on your tree trunks.

The symptoms of this fungal infection vary widely depending on the infected plants. You may notice brownish or pure-white spots on the bark, stems, and branches of your tree. The infected leaves and bark usually look like you’ve sprinkled powder on them. 

If you don’t address the disease early enough, the leaves of the infected tree may turn yellow and fall off prematurely. This occurs when powdery mildew leads to critical nutrient deficiency in the plant. In some cases, white mushroom-like growths develop on the bark of the affected tree. 

Not All White Spots on Trees Are White Fungus

At times, you may mistake the lichen on your trees for white fungus. Lichen can thrive on a wide range of surfaces, including rocks and old, unused cars. 

Unlike white fungi, it isn’t harmful to trees. Also, lichens are not always white. They can be yellow, orange, green, gray, or red. 

White Fungus Prevention & Treatment 

When it comes to preventing or treating white fungus, you must first understand the type of infection you’re dealing with. While heart rot can grievously damage your tree before you notice it, powdery mildew rarely kills the trees that it affects. 

You should protect your trees from wounds and injuries as they can expose your tree to a heart rot infection. A reputable arborist can offer proper advice on how to deal with these fungal infections.
