🌱 How to Care for Honohono Orchid to Prevent Anthracnose?

💧 How to Water

Water every 2-4 days during the growing season (spring through summer), allowing the medium to dry slightly between waterings. In autumn and winter, gradually reduce watering to once a week or less to encourage dormancy and subsequent flowering. Never allow the roots to sit in standing water.

☀️ Lighting

Provide bright indirect light, equivalent to 10,000-30,000 lux. An east- or west-facing windowsill with a sheer curtain is ideal. Insufficient light results in dark green leaves and poor flowering; too much direct sun causes leaf scorch.

🪴 Ideal Soil

Use a fast-draining epiphytic orchid mix of coarse bark, charcoal, and perlite. Hanging wooden baskets or cork bark mounts best replicate natural growing conditions and promote healthy roots. Avoid dense, moisture-retaining mixes.
