When to worry
If the entire base of the plant is mushy and black, it is likely too late to save. Some minor browning at the very tips is normal as old growth dies back.
Stopping it coming back
Keep the plant in a tray of water at all times to mimic its natural bog habitat. Use a loose, peaty soil mix that holds moisture without packing down.

Questions people ask
- Can I use regular potting soil?
- No, regular potting soil is often too dense and lacks the acidity this plant needs. Use a mix heavy in peat or sphagnum moss.
- How often should I check the water level?
- Check it every 1 to 2 days. The soil should never feel dry to the touch.
