Nutrient Requirements: What Does Java Fern Need?

Java Fern is low-maintenance, but two essential nutrients are required:

1. Potassium (K) – The Key Element

2. Phosphorus (P) – Boosts Growth

  • Essential for cell division and new leaf development.
  • Deficiency leads to slow growth and dark green leaves.
  • Usually obtained from fish waste, but can be supplemented with NPK fertilizers.

Propagation of Java Fern

  • Divide the rhizome into smaller sections.
  • The leaves often develop black dots (sporangia), which are reproductive structures.

Yellowing leaves Potassium deficiency Add liquid potassium
Purple spots Phosphorus deficiency Add phosphorus fertilizer
Black dots on leaves Normal (sporangia) No action needed
Slow growth Low light or CO₂ deficiency Increase light, add CO₂
