Root Rot vs. Fungal Leaf Spots on Schefflera

Diagnosing Brown Spots on 6-Year Hawaiian Schefflera

Schefflera with wipe-able brown spots on leaves/stems that return: likely fungal leaf spot, not root rot.

Root Rot Definition

Roots sit in saturated soil → suffocate → rot → turn brown/black, mushy, slough off. Plant wilts despite wet soil. Confirmed only by unpotting.

Leaf Spot vs. Root Rot

• Leaf spots: Fungal (Alternaria, Cercospora). Wipe-able, recurring. Treat with copper fungicide, improve air flow, avoid wet foliage.
• Root rot: Systemic wilt, no leaf spots typically. Fatal if advanced.

Action

1. Copper fungicide spray (top and undersides)
2. Water at soil level only (no foliage wetting)
3. Increase air circulation
4. Check roots if no improvement: unpot, inspect for mush
