Origin and Range : many species native to Burma, India and Thailand. They grow as epiphytes (on trees), from lower elevations up to the cool highlands of the Himalayas. (Up to 4000 feet)
Watering and Nutrition : water when plants are actively growing. As growth slows, reduce the frequency of watering and feeding. Do not over fertilize. For D. nobile type hybrids stop fertilizing in August to encourage flower development.
Light and Shade : provide as much light as possible without burning the leaves. Summering the plants outdoors, will produce strong plants that will flower freely. Small plants will require some shade.
Temperature and Humidity : A night temperature of 60°F (15 C) and 70 to 80°F (20-27 C) during the day is ideal. 50% humidity during the growing season is recommended. Bloom time is generally December to April. For D. nobile type hybrids expose plants to low temperatures [55F (12 C)] for approximately one - two months to initiate flower buds.
Air Circulation : constant air circulation will prevent disease problems and prevent leaf burn from the higher light levels.
Potting : over potting will not enhance the growth of small plants. Repot when the potting mix decomposes or the plant outgrows its container. Repot Dendrobium nobile when they have finished flowering. Do not repot plants in bud or flower. Medium size fir bark with coarse perlite is ideal.
Keep plants moderately lighted or partially shaded with humidity at 60 to 85% with an intermediate night temperatures of 58F to 62F and day temperatures of 75F to 83F. To induce blooming, with hold watering and maintain a cool temperature, ie. 55F during winter nights and expose plant to 9-12 hours of good lighting every day in the winter. plant grow well in bright light; however to get more indeph flower color grow in shade.
Piping Rock Orchids
(armeniacum 'Sunshine' x emersonii 'Doc')
A great combination of the two parents, with creamy white petals, sometimes yellow, along with a darker yellow pouch, with interior spotting that shines through. BS
- Color: White, Yellow
- Light: Low-Medium
- Temperature: Intermediate-Warm
A very rare cross that is one of the best of the parvi hybrids with very large ivory white to creamy yellow flowers with some orange markings in the column area.
