Symptoms and Signs of Root Rot

  • Poor growth: Stunted or slow growth compared to healthy trees.
  • Wilted leaves: Leaves appear wilted or droopy, even when watered adequately.
  • Early leaf drop: Leaves may turn yellow or brown and fall prematurely.
  • Branch dieback: Branches may start dying back from the tips.
  • Decayed roots: Roots may appear soft, mushy, or discolored.
  • Fungal growth: White or gray fungal growth may be visible on or around the roots.

Causes of Tree Root Rot
