Quick Fixes

Immediate unpotting

Remove plant from soil immediately. Every minute counts with crown rot.

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

Plant with crown ABOVE soil level. Mix perlite into soil for extra drainage. Ensure no soil touches the crown.

Initial care

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

Recovery monitoring

🌱 How to Care for Truckee lewisia to Prevent Crown Rot?

💧 How to Water

In the wild it drinks snowmelt in spring and early summer. In the garden, water when the soil is dry, about every 10 days in the growing season, and barely at all in winter. Once established it tolerates drought; what kills it is water sitting around the crown.

☀️ Lighting

Full sun in cool climates. Where summers are hot, give it afternoon shade.

🪴 Ideal Soil

Lean soil with plenty of grit or coarse sand that drains at once. A gravel collar around the crown helps prevent rot. Plant it on its side, in a rock crevice or on a slope, so water does not sit in the rosette.
