4 Ways to Identify Tree Fungi in Vancouver, WA

By AK Timber in Tree Care

Tree fungi is a huge problem in Vancouver, for a few different reasons. The trees we tend to plant, the climate that we have, and even the way we take care of our yards puts a big target on our backs for tree fungi. Unfortunately, many people in Vancouver don’t realize that we have this big problem so they don’t inspect their trees closely enough. This leads to trees that have a fighting chance to survive, but it takes professionals too long to get to them and they fall or are injured beyond repair. However, we do have a fighting chance to save our trees in Vancouver, WA because of one thing: our inspections.

We have long recommended that people inspect their trees at least once per year, if not once every season. This will allow you to know and understand your trees, making it easier to deduce if something goes wrong. Most homeowners won’t do this, and even if they do, the symptoms of the fungus aren’t always easy to spot. Here are a few things you can look for, however:

4. Wounds that Don’t Heal

  • Darker Bark or Bark That is Wet Symbolizes Problems
  • Be Careful When Touching Wounds, Do Not Pierce
  • Start Low on the Tree and Move Up

When you cut your trees, a branch breaks off, or even through just normal wear and tear, you get wounds on the tree. In order to heal these wounds, your trees need to take the time to seal themselves from the outside world. However, they are also susceptible and weak, which is why fungi target these areas of the tree. They will then use the nutrients and water that the tree provides and feast, growing stronger and stronger. Then, the fungi start to feed on the rest of the tree. At this stage, it is difficult to turn back time.

According to Iowa State University, the best way to avoid wounds that won’t heal is to prune properly: “Do not apply wound dressings to pruning cuts. In the past, it was a standard practice to seal pruning cuts with wound dressings or paints. It was thought that wound dressings would keep water, insects, and decay-causing microorganisms from entering the wound.”

3. Yard Moisture

  • Keep Moisture Levels Low if Possible
  • Never Water Infected Trees or Plants Unless Specified
  • Purchase Moisture Monitors

The moister an environment is, the more likely it is to have problems with fungus. This is especially true somewhere like Vancouver, where humidity levels can be quite high. Even worse, living near bodies of water, having water features, or even having a pool can increase the levels of moisture in your yard.

Purchase a yard moisture monitor and use it to determine whether or not your yard is particularly moist this year. If it is, you know that you have to pay more attention to your trees and plants. In particular, pay attention to wounds and other areas where fungus forms.

According to the UGA Extension, you have to pay particular attention to this if you have oak trees. If you do find that you have suspicious looking trees, do not water or hose down those trees. The fungus can spread through the water, which can lead to a total infestation in your yard.

2. Spots on Trunk, Branches, or Leaves

  • Look for White or Black Spots
  • Can Be Flat or 3D
  • Some Wipe Away

Have you ever seen white or black spots on the branches, leaves, or twigs of your trees? If so, you might have seen a fungus in action. When you are pruning your trees or just doing your inspection, take note of any spots that shouldn’t be there. It is quite likely that this is a fungus problem. Some fungus doesn’t actually harm your tree, but many that result in this symptom can have a negative impact.


According to Better Homes and Gardens, “When you see orange, gold, or reddish spots rupturing leaf surfaces, you’re dealing with rust. While it rarely kills plants, rust fungus makes leaves unsightly and weakens the plant by interfering with photosynthesis, the process a plant uses to make food. ”

1. Mushrooms

  • Check Under Shade Cover As Well
  • Act Quickly to Save Tree and Expense
  • Allow Professionals to Remove

Many of us have mushrooms in our yard, and a few types aren’t a sign of anything malevolent taking over our properties. However, if they are on your trees or under the shade cover of the tree, then you might have a problem. Mushrooms that grow along the tree can be a symptom of an infestation that has been around for quite some time.

According to Home Guides, “Bark mushrooms typically grow in the form of conk, also called a bract or shelf. Although some varieties of bark mushrooms are harmless, some cause what is called white rot, and some cause the more serious brown rot. ” This is a serious problem that you need to tackle as soon as you possibly can.

If you see mushrooms, call a professional before removing them or at least take a photo of them so that the team can see what they are fighting.

If you have a fungus on your tree, you don’t have to worry about losing your tree. This is a problem and it can devastate your tree, but it doesn’t have to do so. Instead, you can become proactive and call a professional to handle the situation. Teams of all sizes can handle tree fungi problems in Vancouver.
