Dendrobium Nobile

Water the orchid regularly and keep the soillightly moist. The best way to water is to submerge the pot in a sink of water for a few minutes, making sure to remove all excess water afterwards. During the summer months, or when the temperature is above 75°F (24°C) water your orchid 2-3 times a week. Once a week is adequate when the temperature drops to the lower 70s (21°C). Never water when the temperatures are at or below 50°F (10°C).

Dendrobium nobile is considered an intermediate orchid species, and does particularly well in light diffused by several layers of sheer curtains, or located around 5-7 feet (1.5-2 m) away from an east-facing or a south-facing window. Ideal light parameters are from 1000 to 2000 foot-candles (about 11-22 kilolux). Avoid hot and dry drafts, as well as direct light, as these can damage to the leaves.

The ideal temperature range for Dendrobium nobile is around 80°F (27°C) during the day and around 70°F (21°C) at night. Temperatures over or below this thresholds can harm your orchid. If temperatures do approach the lower limits, cover the plant with sheets or a blanket to keep it warm and avoid damage.

The optimal humidity level for this orchid is about 60-80%, depending on the temperature. In the hot summer months, people can mist the Dendrobium nobile occasionally, but because these plants have adapted to drier climates, they don’t need continual misting. We recommend using a room humidifier to maintain the humidity in a comfortable range.

Dendrobium nobile prefers a slightly damp, but well-draining media. It does particularly well in an orchid bark mix that is capable of holding and releasing the right amount of moisture and nutrients. The PH level of the mix should be about 6.5-7.5, which is slightly acidic. Make sure not to over-pot your orchid, as this can cause root rot.

It’s best to fertilize your Dendrobium nobile regularly during the blooming period, from August to October. Use a balanced fertilizer with equal parts of nitrogen, phosphorus and potassium forthe best results. Fertilize when watering every two weeks or so, and remember to always dilute it to one-fourth of its normal strength to avoid any root burn or potential damage.

Common pests for Dendrobium nobiles include mealy bugs, spider mites and slugs. To prevent any infestations from occurring, make sure to regularly inspect your orchid and handle any potential pests right away. Use a damp cloth to rub off any visible bugs, if necessary. We recommend spraying the foliage of your orchid gently with a bug specific, safe insecticide, until the problem is resolved.

It is recommended to re-pot your Dendrobium nobile once every 1-2 years. The best time to re-pot is towards the end of summer, beginning of fall, when the blooming season is done, or when the orchid is beginning to outgrow its old pot. Choose a pot with draining holes, as this orchid grows best in a slightly damp, but well-draining media. Also, consider using an orchid bark mix to recreate the natural environment of this species.

Dendrobium nobile does not need to be pruned. This orchid re-blooms on its old canes, so it is important to leave them intact and just remove any dried and yellowed leaves. Bloom spikes can be pruned back after they are done flowering, but it is not required.

Unlike many other orchids, Dendrobium nobile does not need to be mulched, as it is already adapted to thrive in drier climates.

Dendrobium nobiles can be propagated by dividing the canes. The best time to do this is during the re-potting process. Make sure to remove any damaged or withered leaves, and cut the stems in a way that each new cutting has at least 3 nodes and 3-4 leaves. The cuttings should then be placed in a damp, well-draining potting mix and monitored for changes every few days. Once the roots are visible, it is a sign that the propagation is successful.

Dendrobium nobile does not require a support structure, as it usually grows close enough to the sides of the pot that it needs no extra support.

During the winter months, the Dendrobium nobile needs a rest period. This means reduced watering, less feeding and lower light levels. If you live in a very cold area, keep your orchid at temperatures of at least 45°F (7°C) to protect it from freezing.

Dendrobium nobiles are not toxic to pets or humans, so feel free to have the orchid around children or furry creatures.
