Root rinse
Rinse roots under lukewarm running water to remove all soil.
Aggressive pruning

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.

π§ How to Water
It is an aquatic/marsh plant: the roots and crown must always remain soaked or submerged, never dry. In an aquarium, maintain a stable water level and perform weekly partial water changes; in a paludarium or pot, keep the substrate constantly saturated or with a shallow layer of water.
βοΈ Lighting
Prefers moderate to strong light, between 8 and 12 hours daily. Low light results in small leaves and slow growth; strong, constant light stimulates larger leaves and, eventually, emerged growth above the water.
