Nepenthes × ‘Amazonica’ Stem Rot: Plant Lost, Lessons for Future

A grower’s N. × ‘Amazonica’ (few months old) suddenly lost all leaves; stem turned brown/mushy. Uprooted, found growth tip rotting, stripped leaves, applied sulfur fungicide, repotted, bagged.

Stem Rot Is Fatal

Once stem rot appears, roots are already gone. This hybrid (all lowland parents) prefers slightly drier, coarser media (add coarse material to sphagnum) and consistent warmth (>65°F nights). It thrives in summer heat but rots easily in cool, short winter days. Plant is dead; apply lessons to next lowlander.
