What’s Wrong With My Tree? Rot Diseases

Rots Can Affect Multiple Parts Of The Tree

rot diseasesRots are a series of diseases that can affect the root, stem, crown, and collar of a tree. They can be caused by fungi, bacteria, and soil-borne nematodes. Common rots include Rhizoctonia and Phytopthora. These fungi prefer drier and wetter soils, respectively, and can enter the tree through wounds. Rhizoctonia infects the tree underground while Phytopthora is a water mold fungus that loves excess moisture and flooding. Both can cause damping-off disease that kills or weakens seeds and seedlings before or after they germinate.

The Signs & Symptoms Of Rot In Trees

Symptoms of rot diseases can vary by what is causing it, but common symptoms include:

  • Tree decline
  • Darkened areas in the bark around the crown and upper roots
  • Dead branches
  • Sunken, dead areas
  • Cankers

Some of these symptoms are most often seen in the late stages of infection.

Preventing Rot Diseases In Trees

To help prevent rot diseases in your trees, make sure that the right tree has been planted in the right place. For example, if a tree that prefers drier soil is planted in an area that regularly floods, problems like root rot is more likely to occur.

Getting your trees regularly inspected by the ISA-certified professionals at Hansen’s Tree Service will help keep your trees healthy and spot problems early. If a problem is spotted, your arborist will give you recommendations for treatment.
