Hygrophila angustifolia (Willow Hygro)

Hygrophila angustifolia (Willow Hygro) is a fast-growing, hardy stem plant from Southeast Asia featuring long, narrow leaves that sway in the water like a weeping willow. It serves as an undemanding, excellent background plant that helps absorb excess nutrients and provides shelter for fish.

Care Requirements

• Lighting:
  Moderate to high; brighter light promotes denser, faster growth and prevents the lower leaves from dying off.

• Water Parameters:
  Temperature range of 22°C–28°C (72°F–82°F) and a pH level between 6.0 and 7.5.

• CO2 and Substrate:
  CO2 injection is not strictly required but accelerates growth; a nutrient-rich substrate or liquid fertilizer helps maintain vibrant green foliage.

Maintenance and Propagation

• Pruning:
  Regular trimming of the top stems encourages a bushier, more compact shape rather than letting it grow tall and thin.

• Propagation:
  Cut a 10–15 cm top section, remove the lower leaves, and plant the stem directly into the substrate to root.
