Troubleshooting Fungus and Algae in Drosera natalensis Seedlings

Managing Fungus and Algae in Pygmy Sundew Seedlings

A grower using steam-distilled water and steamed peat reports white hair-like growths (likely fungus) and mineral deposits on Drosera natalensis seedlings. Despite sterilization efforts, contamination appeared.

Expert Insights

Jake notes that fungus spores are ubiquitous and can survive even steaming. Some seed loss is normal; 100% germination is rare. Over-managing (e.g., rubbing off dew, excessive repotting) harms fragile seedlings.

Best Practices

• Sow seeds on moist, fertilizer-free peat/perlite (1:1).
• Mist daily until germination; then reduce misting as roots develop.
• Use a copper-based fungicide if fungus persists.
• Transplant seedlings by lifting a plug of soil (½–1 inch radius) to minimize root disturbance.

Follow-Up

After accidental dew removal and repotting, seedlings may still recover if roots are intact. New growth should appear within a month.
