Water: Gahnia flourishes in consistently moist environments and prefers regular weekly watering. It has moderate drought tolerance and thrives under stable humidity. Typically found in wetland areas, gahnia benefits from growing seasons with frequent rainfall, providing essential moisture during critical growth phases.

Fertilize: For gahnia, annually enrich the soil with mulch or compost in spring to promote growth and resilience. Use a light layer away from the base to prevent rot. Avoid over-fertilizing by ensuring slow nutrient release, adjusting for seasonal changes to support gahnia's health.

Pruning: Gahnia thrives with early spring pruning to promote new growth and maintain appearance. Remove dead leaves to enhance vigor, manage size, and improve landscaping suitability. Using sharp tools prevents disease, while regular pruning boosts air circulation and light access for overall plant health.

Propagation: Gahnia can be propagated through division by separating clumps into smaller sections, ensuring each segment has roots. Keep divisions moist and plant immediately in well-draining soil. Provide ample water and initial sun protection to enhance establishment and root development success.
