Why Tree Diseases Are a Problem
Your trees are exceptionally vulnerable to several diseases, all of which could drastically reduce their appearance, health, and life expectancy. Many of these diseases infect trunks, causing numerous issues, including premature death.
Although some garden enthusiasts can identify common leaf diseases like powdery mildew or needle disease, spotting a diseased tree trunk can be more complicated. However, once you understand how to identify tree trunk diseases, you can have an arborist treat them before the tree’s health declines beyond help.
Four Tree Trunk Diseases and How to Identify Them
Below are some common tree trunk diseases to watch for and their respective treatment methods.
Rust is one of the most common evergreen diseases. It generates unsightly black, brown, and orange galls along a tree’s trunk, which kill young trees incredibly quickly and spread. The fungal disease often enters through tree wounds and can cause severe structural problems over time.
Spraying infected trees with a fungicide will eliminate the galls and prevent further infection. Neem oil and sulfur will also curb rust and help the tree recover.
Canker is another fungal disease that enters trees through wounds, whether these wounds happen by environmental or human-made factors. The necrotic tendencies decay the infected regions.
Most mature trees won’t die from the disease, but canker quickly kills newly developing plants. The canker infections also discolor tree trunks and cause growth deformities, with canker spots ranging in size. You can generally see them thriving in unhealthy trees with open wounds.
Unfortunately, most canker-infected trees will require removal. If it only affects branches, pruning diseased limbs may prevent it from spreading and promote recovery. However, an arborist would have to make a careful assessment to ensure the canker won’t spread to other trees nearby.
Decays are slow-forming trunk diseases that take several years to set in. Like most trunk diseases, it enters through tree wounds and forms grotesque mushroom-like blemishes (called conks) along the trunk. Although decays aren’t fatal, they drastically weaken the tree and leave it susceptible to damage and other infections.
Decays are relatively easy to spot, as they form multiple conks. Pruning these conks won’t eliminate the problem—arborists use compartmentalization. The diseases take time to eradicate.
Wilt diseases are fatal to trees. They generate burnt leaves without triggering defoliation and form fungi inside the tree’s vessels that restrict crown water saturation. Tree species most vulnerable to wilt diseases include the following:
- Dutch Elm
Don’t Wait Too Long To Address Tree Trunk Issues
Curbing wilt diseases and other issues is incredibly difficult. Pruning infected limbs and applying nitrate nitrogen fertilizer may promote recovery. However, if your trees contract a disease, it’s always best to seek professional care as soon as possible.
