How to grow terrestrial Utricularia (bladderworts)
Terrestrial Utricularia (bladderworts) are carnivorous plants distinguished by numerous small flowers and vacuum traps that capture insects and small organisms in the substrate. Below is a concise guide on How to grow terrestrial Utricularia (bladderworts), organized by the 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 daily periods.
Temperature: Most species prefer standard room temperatures.
Substrate: Use clean fibrous peat mixed with silica sand or perlite in a 2:1 ratio.
Humidity: Most species grow well even at regular room humidity. Increased air humidity will enhance growth and vitality.
Watering: The plants should always stand in water. Water from below by placing the pot in a tray. Some species require the water level to reach the substrate’s surface.
Fertilizing: Substrates naturally contain tiny organisms that the plants capture. They have enough prey all year round, so additional feeding is unnecessary. Other forms of fertilizing are unsuitable.
