Nepenthes northiana problems — and how to fix them
Nepenthes northiana (Nepenthes northiana) 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.
Weak peristome colour
Insufficient light dulls the signature striped peristome. Increase bright light, including a little direct sun, to bring out the colour.
Pitchers not forming
Low humidity is the usual cause. Raise humidity above 70% and keep conditions stable to encourage pitcher production.
Mineral damage
Tap water salts brown the leaf margins and stunt growth. Switch to rainwater or RO and flush the media regularly.
Root rot in dense media
Compacted or soggy substrate suffocates roots. Use an open sphagnum/perlite mix and ensure pots drain freely.
