How to Diagnose
If you suspect root rot, unpot the plant. Healthy roots are white to cream and firm. Rotted roots are brown to black, soft, mushy, and may smell. The severity determines the treatment approach.
Treatment
Remove all rotted roots with clean scissors. Dust cut ends with cinnamon or powdered charcoal (natural antifungals). Let roots air-dry 30–60 minutes. Repot into fresh, well-draining compost in a clean pot with drainage holes. Don't water for 2–3 days after repotting.
Prevention
Never let pots sit in standing water. Always use pots with drainage holes. Use well-draining compost (add perlite). Water only when the top layer of soil has dried out. Choose an appropriately sized pot — not too large.
