Planting And Propagation Techniques

Java Fern is a popular plant for ornamental fish tanks. It is easy to grow and helps create a natural look.

Knowing how to plant and propagate Java Fern helps keep it healthy and growing well in your aquarium.

Attaching To Driftwood And Rocks

Java Fern roots do not need soil to grow. They attach well to driftwood and rocks. Use fishing line or thread to tie the plant to the surface.

After a few weeks, the plant’s roots will hold firmly. Remove the thread carefully to avoid damage.

  • Place Java Fern on driftwood or rock surface
  • Secure with fishing line or thread
  • Wait for roots to attach firmly

Division And Rhizome Cutting

Java Fern grows from a thick rhizome. You can divide the plant by cutting the rhizome into pieces. Each piece must have leaves and roots.

  • Cut rhizome into sections with leaves and roots
  • Attach each section to driftwood or rock
  • Keep in low to medium light
  • Watch new growth appear in weeks

Avoiding Planting In Substrate

Java Fern should not be planted in the tank’s substrate. Burying the rhizome can cause it to rot. Only roots can touch the substrate.

Keep the rhizome above the substrate surface. This keeps the plant healthy and growing well over time.

  • Allow roots to grow into substrate only
  • Attach rhizome to wood or rock instead
  • Check plant health regularly
