Quick Fixes
Immediate unpotting
Remove plant from soil immediately. Every minute counts with crown rot.
Rapid rinse
Rinse all soil off under running water. Inspect crown for extent of damage.
Aggressive pruning
Cut away ALL discolored tissue without hesitation. Better to over-prune than leave any infected tissue.
Hydrogen peroxide treatment
Spray or dip crown and roots in 3% hydrogen peroxide solution. This kills pathogens instantly and oxygenates tissue.
Quick dry
Pat dry with paper towels and air dry for 1 hour in front of a fan.
Fast repot
Plant in completely DRY, fresh cactus mix with crown elevated above soil. Do NOT water.
Strict water ban
Absolutely no water for 5-7 days. Place in bright indirect light with good airflow.
Minimal watering protocol
Resume watering only when soil is bone dry. Use half the normal amount.
Organic Treatment
Emergency removal
Immediately remove the plant from its pot. Speed is critical to save any healthy tissue.
Thorough cleaning
Gently wash all soil from roots and crown using lukewarm water. Examine the entire crown area carefully.
Surgical tissue removal
Using sterile scissors, cut away ALL brown, black, or mushy tissue from the crown and roots. Cut back to firm, healthy tissue.
Cinnamon treatment
Generously dust all cut surfaces with cinnamon powder. This acts as a natural fungicide and prevents regrowth.
Chamomile soak
Brew strong chamomile tea (3-4 bags), let cool completely. Soak the crown and roots for 20-30 minutes.
Air drying period
Let the plant air dry in a shaded, well-ventilated area for 3-4 hours. Crown should be completely dry.
Prepare clean container
Sterilize pot with diluted vinegar (1:4 ratio), rinse thoroughly, and dry. Fill with fresh cactus/succulent mix for superior drainage.
Careful replanting

Initial care
Do NOT water for 5-7 days. Place in bright indirect light with excellent air circulation.
