Algae on Nepenthes truncata Seedling Moss: Repot for Better Drainage

A grower's Christmas N. truncata 'Queen of Hearts × King of Spades' in dried long-fiber sphagnum shows green surface growth (algae). Sulfur fungicide didn't help. Plant is pitchering and growing on a Tacoma windowsill.

Solution

Repot into a larger pot (double size) with fresh mix. Algae indicates media stays too wet. Larger pot = less frequent watering, damp not wet surface. Longer spring days will also reduce algae.
