Light Requirements
Unlike other orchid plants, Dendrobium Nobile orchids need bright light for 365 days. They can tolerate very bright light.
This encourages plants to produce a greater number of scented flowers. In the winter season, you need to put the plant pot in a sunny window.
Because in winter sun emits low intense light. But this plant needs medium intense light waves.
To fully fill its light needs you should put the plant pot in direct sunlight on cool days of the winter season.
South window is best on winter days. But if you do not have a window then the only option is to use grow lights.
On the other hand, the extra bright light causes many problems in orchid plants. Faded leaves, and burn leaf tips are the first signs of over-light exposure.
In the case of grow lights, do not choose HPS to grow lights. They produce a high amount of heat.
They are good to grow vegetable crops. Whereas houseplants are delicate plants they need soft light to grow.
Therefore, LED grow lights are best to use. They do not release a high amount of heat and also consume very little energy. LEDs are energy-efficient grow lights.
NASA also uses them in Space to grow plants.

Watering Dendrobium Nobile orchids
Dendrobium Nobile orchids need different amounts of water in different seasons of the year. In the summer months, it needs more water, not due to the hot weather.

Humidity

These plants are tolerant to temperature variations. It can handle sudden increases and decreases in the grow room temperature.
But for the good care you need to maintain the same temperature in the room for 365 days.
Fertilizer
Use liquid-type water-soluble fertilizer once every 2 weeks in the active growing stage.
To play safe use half the dosage than the recommendation. Using strong fertilizer will burn the plant leaves and cause over-fertilization issues.
Do not use them on cool days. Stop it from October to march. This is the dormancy period of all houseplants.
They do not grow in this time period. Do not think that indoor plants will grow on winter days.
They will not grow even if you put them in the ideal growing conditions.
This is the law of mother nature. Every living thing on earth slows down its growing phase in the winter months.
Pruning
It is a necessary part of Dendrobium Nobile orchids care. Flowers grow on plant cane. Once the bloom time is over.
Then you need to cut the flower spikes.
These spikes are attached to plant canes. Do not cut the canes because the flowers will again bloom on the cane.
Also, remove the yellow and dead parts of the plants.
Note: For pruning use sterilized garden tools.
Repotting
Dendrobium Nobile orchids is a root-bounding plant. It needs repotting every 2 to 3 years.
Do not use too big a size pot this will result in root rot-like issues. Only one size bigger poot is ideal for repotting Dendrobium orchids.
Repot it in its active stage when the plant just finishes the bloom.
Carefully take out the plant from its pot and put it in another big pot. Do not use the same potting soil. You should use new potting soil of the same type in the new pot.
At the time of repotting inspect the plant roots. If you see any sign of infection remove the infected part of the roots with sharp shears. Then plant it in the new pot.
Give some water and put it in its final place. Then repeat the care steps your plant will adapt to its new pot in a few days.
Common problems
Yellow leaves
