Troubleshooting
Nepenthes macrophylla problems — and how to fix them
Nepenthes macrophylla (Nepenthes macrophylla) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
No cool night drop
Highland species fail without nights around 8-15°C. Without the drop they stop pitchering and decline; provide a cool grow space or chiller.
Pitchers fail to form
Low humidity or weak light. Raise humidity above 70% and increase light intensity to trigger pitcher development.
Mineral burn / brown leaf tips
Tap water or fertiliser salts accumulate and scorch foliage. Use only pure water and flush the media periodically.
Fungal spotting on large leaves
High humidity with stagnant air invites mould. Add a gentle fan and avoid wetting leaves late in the day.
