Rescuing Drosera Seedlings from Algae and Fungus Contamination

Partial Transplant to Save Seedlings from Algae/Fungus

A grower's D. natalensis seedlings face white growth on algae; the tray dried out completely. They ask if algae turns white and whether seedlings will survive.

Expert Solution

Answer: Some algae is white, but so are many fungi. If seedlings are healthy, do a partial transplant: dig out each seedling with a small soil plug (½ inch radius, 1–2 inches deep) and move to fresh, sterile media. This leaves contaminants behind.

Prevention

• Keep trays consistently moist (never bone dry).
• Sterilize media by boiling.
• Use pure water (distilled/RO/rain).
