The cause of root rot is a fungus. Species of the Pythium, Phytophthora, Rhizoctonia, or Fusarium fungi are the usual culprits is caused by poor drainage or overwatering in the soil around the tree. The tree becomes unable to absorb the moisture and nourishment it needs from the soil, causing the oxygen-starved roots to slowly die and decay.

In some trees, it can take years of suffering from this disease before it dies. In others, the tree may be killed within a single season.

How to prevent root rot

Preventing root rot starts with good soil drainage. Avoid overwatering and creating irrigation moats to keep water from pooling against the trunk. Proper care and drainage is particularly important for young trees, as they are especially vulnerable due to underdeveloped root systems and crowns.
