🌱 How to Care for Ascocentrum orchid to Prevent Mealybugs?

💧 How to Water

Water thoroughly until the roots turn green, then let them dry and turn silvery-white before watering again. In warm months this can be daily for bare-root or mounted plants; in winter water less often. Use rainwater or low-mineral water and never leave water standing in the leaf axils.

☀️ Lighting

Give strong, bright light similar to a Vanda or Cattleya: an east or south window or a bright greenhouse spot with some morning or late-afternoon sun. Too little light stops flowering, but harsh midday sun through glass can scorch the leaves, so acclimate it gradually.

🪴 Ideal Soil

Use little or no potting mix. Grow it bare-root in a wooden slat basket, mounted on cork or bark, or in a small pot with very coarse bark and charcoal so the roots get air and dry quickly.
