How to Care for a Dendrobium Unicum and Grow It?
That’s fairly simple! You can grow it in pots or mount it to tree ferns and corks. However, remember, repotting and planting should be done in early spring.
What Pots to Use
Our florists recommend using small-sized pots for this plant.
During the growth season, you will need to water the plant copiously. Also, ensure that the potting material does not become dry in between watering.
The plant needs shading from spring to autumn, and you should expose it to only medium lighting levels. Many florists recommend keeping these indoors somewhere where there is adequate light.
How Often Do You Water the Unicum?
Since these plants are native to regions that receive heavy rainfalls in summer, you will need to water them during the bloom copiously. As mentioned above, the media should not be allowed to dry up completely.
It is recommended to use regular water instead of salt-softened and distilled water. How much you should water them also varies depending on the type of potting media used by considering the material and size of the pot.
How to Fertilize the Dendrobium Unicum?
As for fertilizer, you will need to fertilize this plant once at least every week. It is best to use a fertilizer that is high in nitrogen to use during spring to mid-summer. Another one that is high in phosphorus is recommended to be used during late summer through autumn.
It is also a useful practice to mix the fertilizer at half or one-fourth the strength recommended by the manufacturer. Once a month, you should use clear water to wash the potting mixture in order to remove any accumulated residual salts from the fertilizer.
How Much Light Does It Require?
This plant needs only a moderate amount of light. An approximate amount usually recommended by experts is 25,000 to 40,000 lux. You can put it under direct sunlight as long as the light is not intense enough to burn it. However, we strongly advise you to place it under a shade or indoors near a light source.
What Is the Appropriate Amount of Humidity Needed for Growing Dendrobium Unicum?
This plant is native to very humid lands. It thrives in humidity levels as high as 80-85 percent in summers and autumn. During non-growth periods of winters, this level falls to 55 percent.
If you live in areas with low humidity levels, you can use a humidifier for your dendrobium. We have also found that using a shallow tray filled with pebbles around your pot also tends to increase the humidity levels around the plant. However, if you do so, ensure that the pot is not touching the water since this will lead to the roots rotting away.
How to Care For Dendrobium During Non-Growth Periods?
Fortunately, Dendrobium is very low-maintenance during its rest phases which last from fall till spring. During these five to six months, you can continue to water them less and less. It becomes possible to allow the potting material to become dry for a while in between watering.
You will also not need to fertilize the plant during the non-blooming period or worry about humidity levels, given that the plant is not exposed to very high variations in temperature and lighting.
During the non-bloom period, you can cut or prune the flowering stems after they emerge from the thin pseudo-bulbs. Don’t cut the pseudo-bulb, though, as no bloom would occur afterward.
Ideal Temperatures for Dendrobium Unicum
This orchid can withstand a wide variation of temperature, especially hotter temperatures, if you allow for adequate humidity and ventilation.
The ideal temperature is between 65 to 75 Fahrenheit during the daytime and 55 to 60 Fahrenheit during the night.
How Important Is Ventilation for This Plant?
It is vital to maintain proper ventilation near your Dendrobium unicum. If these plants are crowded with each other or other plants, it can lead to insect and fungal infestations. Make sure that this particular species gets the space it needs to thrive.
Repotting Dendrobium Unicum
Keep in mind the following pointers while repotting your Dendrobium Unicum;
- Dendrobium unicum should be repotted every two to three years.
- The ideal time of the year for repotting is early spring.
- You should always use a small pot for these orchids. It is because larger pots tend to slow down growth and produce fewer flowers.
What Does Dendrobium Unicum Smell Like?
This southeast Asian orchid variety exhibits quite a number of fragrances. It has been commonly known to smell like fresh tangerines, which is just the smell you want around you in the summertime.
Some varieties also smell of freshly sharpened crayons or Crayola wax. Not bad either, right? Unfortunately, sometimes this plant has been observed not to exhibit any type of fragrance at all as well.
