Gießen
Always keep the plant fully submerged in water.
Düngen
Do not fertilize, as this plant captures its own nutrients from prey.
Schneiden
Trim back excess growth if the plant begins to crowd its container.
Umtopfen
Repotting is not applicable since it is a free floating aquatic plant.

Anzeichen fürs Umtopfen

  • The container becomes overcrowded with plant mass.
  • Water quality begins to decline due to excessive biomass.

Häufige Probleme

  • Algae overgrowth — Excessive algae can shade out the plant and compete for nutrients.

Standort und Pflege

Vermehrung
division, seed, turions
Pflanzzeit
spring
Überwinterung
In cold climates, the plant will form turions that sink to the bottom of the pond. Leave these undisturbed until spring when they will naturally rise to the surface.
Im Kübel
It is perfectly suited for containers, provided you use a pond or bowl with at least 10 liters of water.

Division

  1. 1. Gently pull a section of the plant away from the main mass.
  2. 2. Place the cutting into a new container of clean, stagnant water.
  3. 3. Ensure the container receives bright, indirect sunlight.

Ensure the water remains clear of excessive algae to allow enough light for the bladder traps to function.

Gute Pflanzpartner

  • Nymphaea — They share similar water requirements and provide complementary foliage textures.
  • Ceratophyllum demersum — Both are free floating plants that help oxygenate the water.

Ähnliche Arten

  • Utricularia minor — A smaller relative with similar growth habits.

Häufige Fragen

Does it need soil?
No, it is a free floating aquatic plant that absorbs nutrients directly from the water.
Will it eat my fish?
No, the traps are only large enough to capture tiny microorganisms like daphnia.

Woher der Name kommt

The name Utricularia comes from the Latin word utriculus, meaning little bottle, referring to the bladder traps. The species name vulgaris simply means common.

Gut zu wissen

  • It is a rootless aquatic plant that floats freely in the water.
  • The traps are among the fastest moving structures in the plant kingdom.
  • It produces winter buds called turions that sink to the bottom to survive cold weather.
