Water: Blunt-leaved orchid prefers consistent hydration, thriving in stable moisture rather than extremes. Water weekly and use well-draining soil to prevent root rot, especially in indoor settings, mimicking its moist natural environment for optimal growth.

Fertilize: For blunt-leaved orchid, use balanced fertilizers to promote growth. Apply diluted fertilizer bi-weekly in spring and summer, reducing to monthly in fall, and withholding in winter. Water before fertilizing to avoid root burn. Adjust feeding based on plant response and use half the recommended strength.

Pruning: Blunt-leaved orchid features rounded leaves and delicate flowers, needing light pruning primarily in early to late spring. Remove dead foliage and spent spikes to encourage growth and blooms, while preventing disease. Always sterilize tools to avoid infections.

Propagation: Blunt-leaved orchid is a terrestrial orchid requiring careful propagation through rhizome division, ensuring each section has a pseudo-bulb. High humidity and shade are essential post-division, along with a well-draining, moisture-retentive medium. Proper watering supports growth while preventing rot.
