LIGHT
Nobile Dendrobium orchids require lots of light. No shade is required during the winter months, and only about 30% shading is suggested during the summer months. With this amount of light, good air circulation is a must to keep leaves from burning.
WATERING​
A direct relationship exists between temperature, light, and watering. As temps begin to rise in the spring, watering should be gradually increased. In the warm summer months, water frequently to keep plants from drying. As temps decline during the fall, reduce watering. During the cold winter months, water only enough to keep the canes from shriveling – about 2 or 3 times a month. Water temps should feel tepid to the touch.
TEMPERATURE
Nobile Dendrobiums orchids prefer temperatures ranging from 55 – 85 degrees. Lower temps around 50 degrees for about a month are needed to initiate flowering. Try placing the plants in a cool window or outside to initiate flowering. Stagnant air should be avoided with all orchids.
FERTILIZER
Use fertilizer sparingly with all orchids. Nobile Dendrobium orchids like to have a high nitrogen mix to initiate plant growth. If potted in a bark mix, use 30-10-10. Withhold all fertilizer in winter.
Our Advice
 Do not overpot Nobile Dendrobium orchids. The plants usually appear to be too small a pot—bark mixed with charcoal, sphagnum moss to maintain healthy roots. Osmunda and tree fern can all be used as potting media.
