White Mold on Nepenthes Soil: Repot or Treat?

Weylin's Nepenthes (labeled "Nepenthes ?") has white fungal growth on soil surface—only plant affected. Grown on a windowsill with distilled water.

Nepenthes ?

Jeff Dallas: Good opportunity to repot if a larger pot is desired. To prevent future mold: top-water more (washes spores away) and/or use low-toxicity sulfur fungicide.

Good Growing!
