ðą How to Care for Closterium Dendrobium to Prevent Scale Insects?
ð§ How to Water
Water year-round, allowing the mount or mix to approach dryness between waterings; increase frequency during active spring-summer growth and ease off slightly afterward, since this species does not have a pronounced dry dormancy like many deciduous Dendrobiums.
âïļ Lighting
Provide bright, filtered light with some direct morning sun; avoid harsh midday sun which can scorch the leathery leaves.
ðŠī Ideal Soil
Mount on bark or cork, or use a small pot/basket with a very open, fast-draining orchid mix (bark chips, charcoal, sphagnum); good drainage and airflow around the roots is essential.
