Water: Formosa palm flourishes in subtropical climates with consistent moisture and high humidity. It tolerates moderate drought but prefers regular humidity. Water bi-weekly to replicate these conditions. As an evergreen, formosa palm retains moisture year-round, suitable for indoor or outdoor growing based on climate adaptability.

Fertilize: For optimal growth, formosa palm needs balanced nutrition, favoring high nitrogen during the growth season. Use slow-release fertilizer every 2-3 months, reducing in winter. Careful application prevents root damage; avoid over-fertilizing. Handle with gloves, keeping fertilizer off leaves and stems for safety.

Pruning: Pruning formosa palm in early spring enhances its health and appearance. Remove dead fronds and thin overcrowded growth for better air circulation. Cut spent flower stalks to promote new growth. Always use clean, sharp tools to reduce infection risks, ensuring a vigorous plant.

Propagation: Formosa palm can be propagated by dividing its clumps; separate offshoots while preserving roots. Plant in well-draining soil with moisture in a warm, humid environment. Monitor for root establishment and provide consistent watering for successful propagation.

Repotting: Repot formosa palm every 1-2 years in spring. Use a larger pot and well-draining soil for root growth. Water moderately and provide bright, indirect light to support adjustment and growth.
