Tropical pitcher plant problems — and how to fix them

Tropical pitcher plant (Nepenthes (tropical pitcher plant)) 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 new pitchers forming

Almost always too little humidity, or a sudden change in light, temperature or position; leaves still grow but the tendrils fail to swell into pitchers. Raise humidity and keep conditions stable while it re-establishes.

Brown leaf tips and crispy edges

The hallmark of tap or mineral water poisoning the roots, or air that is too dry. Switch to rainwater, distilled or RO water immediately and flush the pot to wash out accumulated salts.

Pitchers blackening and rotting

Usually overfeeding, feeding meat or fertiliser, or stagnant overly wet conditions. Feed only tiny insects sparingly, improve airflow, and trim spent pitchers; some natural ageing and browning of older pitchers is normal.

Pale, spindly, floppy growth

Not enough light. Move to a brighter spot or add a grow light; healthy plants show compact growth and often a reddish blush on stems and pitchers in good light.
