Quick Fixes
Emergency unpotting
Remove plant immediately from wet soil. Speed is critical.
Root rinse
Rinse roots under lukewarm running water to remove all soil.
Aggressive pruning
Cut away ALL affected roots without hesitation. Its better to over-prune than leave infected tissue.
Peroxide treatment
Spray or dip roots in 3% hydrogen peroxide solution. This kills pathogens and oxygenates tissue.
Quick dry
Pat roots with paper towels and let air dry for 30-60 minutes.
Fast repot
Repot in completely dry, fresh potting mix. Do not water for 3-5 days.
Stress reduction
Place in bright indirect light, away from direct sun. Reduce watering frequency significantly.
Organic Treatment
Remove and assess
Carefully remove the plant from its pot and gently wash away all soil from the roots. Assess the extent of root damage.
Prune affected roots
Using sterile scissors, cut away all soft, mushy, brown, or black roots. Cut back to healthy white tissue.
Apply cinnamon
Dust all cut surfaces generously with cinnamon powder to prevent fungal regrowth.
Prepare chamomile soak
Brew strong chamomile tea and let it cool. Soak the remaining roots for 15-20 minutes.
Air dry roots
Let the roots air dry for 2-4 hours in a shaded area with good air circulation.
Prepare new container
Clean the pot with diluted vinegar, rinse well, and fill with fresh sterile potting mix.
Repot carefully
Plant in the new soil, ensuring the root crown is at the proper level.
Initial watering
Water lightly with diluted neem oil solution (1 tsp per liter of water).
