How to grow epiphytic Utricularia (bladderworts)
Epiphytic bladderworts (large-flowered) are carnivorous plants notable for their numerous large blooms and vacuum traps, which catch insects and small organisms in the substrate. Here is a concise guide on How to grow epiphytic Utricularia (bladderworts), divided by the specific conditions they require:
Light conditions: Provide maximum diffused light. An east- or west-facing window is ideal. They also thrive under artificial lighting without natural light or changing day periods.
Temperature: Most species prefer typical room temperatures. More demanding mountain species require nighttime temperature drops to flower successfully.
Substrate: They need an airy substrate. Use clean fibrous peat with perlite and pine bark as a base. Sphagnum moss is also excellent. Mix all components in similar proportions.
Air humidity: Most species grow well even in regular room humidity. Higher air humidity enhances growth and vitality.
Watering: Keep the substrate consistently moist. Avoid letting the plants sit in water to prevent rot.
Fertilizing: Substrates naturally contain tiny organisms that the plants capture. They have ample prey throughout the year, so additional feeding is unnecessary. Other forms of fertilizing are unsuitable.
