ðą How to Care for Ascocentrum orchid to Prevent Grey Mould?
ð§ 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.
âïļ 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.
ðŠī 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.
