Under certain conditions, trees develop root rot, a disease that affects tree roots growing in damp or wet soil. The type of tree services needed depends on the cause and extent of damage. This guide will help you identify the problem and take steps to control and prevent the disease. 

How Root Rot Develops

The predominant cause of root rot is soil that drains poorly or receives excessive water. Roots need plenty of oxygen to live, and soggy soil stops roots from absorbing what it needs. The roots die and rot without oxygen. Even when the sogginess ends, the rotting can spread to healthy roots. 

Rot also occurs in weak roots, which are more likely to develop soil fungus than healthy roots. Fungal spores, including Pythium, Phytophthora, and Fusarium, remain dormant for years. However, when soils become too wet, the dampness revives the spores. They attack the roots and cause damage. 

Signs

Properly identifying root rot signs can be difficult, because they resemble pest infestation. Indications include leaves that are pale, small, yellowed, brown or wilted. 

Other signs include poor or stunted growth, or a decline in health without an apparent reason. A canopy thinning or branches dying back can mean root rot. Careful digging to the root to examine it is the most accurate way to determine if there is root rot. 

How to Prevent It and Control the Spread

To prevent root rot, consider growing cover crops, such as mustard, canola, and forage radish. These temporary plants supply soil with nutrients that help trees thrive. They also destroy the cycles of diseases including Fusarium. 

Adjusting the pH of the soil and avoiding conditions that stress your trees, such as drought or over-watering, helps them resist developing root rot. Controlling the disease's spread may require a tree services professional to prune the roots. Severe cases might require removing the entire tree and applying chloropicrin or methyl bromide to the surrounding grounds.
