Controlling Mold in Drosera spatulata: Watering, Light, and Fungicide

Mold Management for Tropical Sundews Indoors

A grower's D. spatulata in a small container (bottom-watered, ¼" water, 6500K lights 10–12 hrs) has a dead, molding plant. They consider springtails and ask for fungicide recommendations.

Expert Strategies

• Top-water frequently to wash spores off leaves.
• Remove dead leaves promptly—mold starts there.
• Place plants close to lights (strong UV suppresses mold). D. spatulata wants full sun; dark red new growth indicates adequate light.
• Preventative fungicide: Safer sulfur-based fungicide. See podcast on safe fungicides.

Springtails

Not necessary if cultural practices are corrected. They help with decomposition but don't replace good hygiene.
