Light
Strong, intense light. Heliamphora are less forgiving of low light than most other carnivorous plants, and need a powerful grow light or LED setup for healthy, colourful growth. Natural sunlight can help as a supplement. Grow lights can be positioned quite close to the plant because of this high light requirement, and a strong LED setup run 14 to 15 hours a day works well.
Soil
1 part long-fibre sphagnum moss to 1 part perlite. Orchid bark can be added to the mix, further improving aeration and providing a damp medium for roots to secure to. The media should stay airy and open. Live sphagnum also does well growing on top of the media.
Use plastic or glazed pots rather than unglazed terracotta, which dries out fast and can slowly leach minerals into the mix.
Prefer it ready-made? Get the potting mix we use.
Water
Keep media damp using rainwater, distilled water, or reverse osmosis water. Water from the top and let it drain freely rather than leaving the pot in deep standing water.
Heliamphora are the most sensitive plants we sell when it comes to mineral buildup, so pure water matters more here than with anything else.
Humidity
Aim for 60% or higher. An enclosed terrarium or cabinet is the easiest way to hold that in a Canadian home. Growers do succeed in open room air too, as long as temperatures stay cool and steady with decent air movement.
Temperature
Wants it cool, especially at night, roughly 16 to 27°C. Sustained heat above about 30°C is the main risk. Our mild coastal BC climate is a real advantage for this plant compared to most of the rest of Canada.
Dormancy
None needed. Heliamphora want steady, cool, humid conditions all year rather than a winter rest.
Feeding & Fertilizer
Never fertilize the soil. A Heliamphora's roots are extremely sensitive to fertilizer.
A diluted liquid fertilizer or a small dried insect dropped into a pitcher once a month is plenty.
Pruning & Repotting
Trimming
Trim pitchers off once they've browned fully. Older pitchers dying back while new ones open is normal.
Repotting & dividing
Repot every 2 to 3 years into fresh media, or whenever the sphagnum breaks down and stops draining freely. Clumps can be divided at the same time, separating rosettes that have roots of their own.
