Noble Dendrobium Dendrobium nobile
ABOUT
Dendrobium nobile, commonly known as the Noble Dendrobium, is an eye-catching orchid species with a striking appearance. The plant is characterized by its long, slender stems that branch out elegantly. These stems often have a somewhat bamboo-like look, both in terms of their segmented nature and the occasional leaf that sprouts from their nodes. The leaves of the Noble Dendrobium are a deep, rich green, and their shape is elongated, tending to curve gracefully. They have a smooth texture and are quite leathery to the touch. The foliage provides a lush backdrop for the plant's most spectacular feature - its blossoms. Flowers of the Noble Dendrobium are undoubtedly the stars of the show. They grow in clusters along the stem and can range in color from pure white to pale pink or even deep purple. Each blossom exhibits a symmetrical shape and boasts an attractive, waxy quality. The petals and sepals spread out from the center of the flower, framing the distinctive lip, which is often a contrasting color adorned with unique markings or patterns. The lip, a modified petal typical to orchids, serves as a landing pad for pollinators and can have various shapes and textures distinct from the rest of the flower. The blossoms of the Noble Dendrobium carry a pleasing fragrance and can bloom for several months under optimal conditions, providing a long-lasting display of floral beauty. The overall appearance of the plant is one of tropical elegance and vibrant life.

WaterNoble Dendrobium orchids should be watered once every week to ten days, allowing the potting medium to dry out slightly between waterings. Apply enough water to see it run freely from the bottom of the pot, ensuring thorough saturation of the potting medium. Depending on the size of the pot, this might be equivalent to about 8 to 16 ounces of water per watering session. During the active growth phase in spring and summer, watering frequency may increase due to higher light and temperature conditions, but always check the moisture level before watering.
LightNoble Dendrobium orchids thrive in bright, indirect light conditions. They should be placed in an east or west-facing window where they receive some direct sun during the morning or late afternoon. Avoid direct midday sun, which can be too intense and may scorch the leaves. If natural light is insufficient, supplement with grow lights to mimic the orchid's preferred lighting conditions.
TemperatureNoble Dendrobium orchids prefer temperatures ranging from 50 to 70 degrees Fahrenheit at night, with a daytime range of 60 to 85 degrees Fahrenheit. They can tolerate temperatures as high as 95 degrees Fahrenheit if shading and increased humidity are provided. It's essential to avoid exposure to temperatures below 50 degrees Fahrenheit as these can be detrimental to the plant's health.
PruningPrune Noble Dendrobium orchids to remove spent flower stems and to maintain plant shape. Pruning should be done after the orchid has finished blooming, typically in the late winter or early spring. Cut back the flower stalks to the base of the plant using sterile pruning shears. It is also a good practice to remove any dead or yellowing leaves to ensure the plant's energy is directed towards new growth.
CleaningAs needed
SoilThe Noble Dendrobium orchid thrives in a well-draining, orchid-specific mix composed of bark, charcoal, and perlite. The ideal soil pH for Dendrobium nobile should be slightly acidic to neutral, in the range of 5.5 to 7.0. Regularly inspect for decomposition and refresh the mix to prevent waterlogging.
RepottingNoble Dendrobium orchids should be repotted every 2 to 3 years, preferably in the spring after flowering. Choose a pot only slightly larger than the previous one to avoid excess moisture retention which can lead to root rot.
Humidity & MistingNoble Dendrobium orchids prefer high humidity, ideally between 50-70%. Consistent higher humidity is crucial for their growth, bearing in mind adequate air circulation to prevent diseases.
Suitable locationsIndoor
Place Noble Dendrobium in bright light, away from direct sun, ensure high humidity and good airflow.
Outdoor
Provide dappled light, protect from intense sun and frost, ensure high humidity levels.

Life cycleThe life of the Dendrobium nobile, commonly known as the Noble Dendrobium orchid, begins with the germination of tiny seeds that require a symbiotic relationship with a mycorrhizal fungus to provide the necessary nutrients. Following germination, the plant develops a protocorm, which is an intermediary organ between seed and seedling, eventually giving rise to the first leaves and roots. As the orchid matures, it forms pseudobulbs, which are swollen stems that serve as storage organs for water and nutrients, essential for the plant's growth and flowering. The orchid reaches maturity and enters its flowering stage, blooming with a spectacular array of flowers that can last several weeks to months. After pollination, which is often facilitated by insects, the flowers develop into fruiting capsules containing numerous dust-like seeds, thereby completing the reproductive cycle. Finally, the plant may enter a period of dormancy, particularly in cooler climates, during which growth slows down or ceases until conditions become favorable again.
PropogationPropogation time
Spring-Early Summer
Propogation: The most popular method of propagation for Dendrobium nobile, commonly known as the Noble Dendrobium, is through division. This process is typically done in the spring, just after the plant has finished flowering, when the plant is starting to produce new growth. To propagate by division, carefully remove the plant from its container and gently separate the pseudobulbs, ensuring that each division has at least one healthy cane and a good root system. After the division, the cut surfaces should be treated with a fungicide to prevent infection. Then, pot each division into a suitable orchid potting mix, ideally in small pots that snugly fit the size of the roots, which allows for better control of moisture. It's important to maintain high humidity and consistent watering after repotting to encourage new growth and help the divisions establish.
