Requirements to Grow Dendrobium Nobile

Sunlight

Noble Rock Orchid thrives in bright, indirect sunlight. Place it in a location where it can receive filtered or dappled sunlight throughout the day.

In addition, avoid exposing it to direct, intense sunlight, as it can scorch the leaves. A shaded area with good natural light is ideal.

Soil

Dendrobium nobile is an epiphytic orchid that prefers well-draining orchid-specific potting mix. A mix of bark, sphagnum moss, and perlite works well.

Ensure the potting mix allows good air circulation around the roots and provides support for the plant. Avoid heavy soils that retain excessive moisture.

Water

Water Dendrobium nobile thoroughly when the potting mix starts to dry out. During the active growing season, typically spring and summer, water more frequently, allowing the top inch of the mix to dry between waterings.

Additionally, reduce watering during the rest period in late fall and winter. Avoid overwatering, as it can lead to root rot.
