You may not have to water it as much during the blooming time, which usually starts from mid to late November. Reduce the watering to every couple of weeks. Keep the reduced watering till the buds start appearing on the plant. 

Light

It needs bright sunlight for six to eight hours a day. But don’t place it directly in the sunlight as it may burn the delicate flowers.

Temperature

Dendrobium Nobile grows best when the temperature is between 15 and 21-degree Celsius (59 F to 70 F). It blooms during fall when the temperature is a bit mild. In the wintertime, maintain the 15 to 24-degree Celsius temperature during the day and 10 to 14 degrees Celsius at night.

If you are planting it indoors, then you can place it outside where it gets the proper sunlight during the day. Then move it inside when the temperature starts dropping. 

Fertilizer

Dendrobium Nobile doesn’t need much fertilizer, but during a blooming period, you can use a 20-10-20 fertilizer. Don’t over-fertilize as it results in stronger growth of the foliage than the flower.

How to Pot and Repot 

Dendrobium Nobile takes time to grow its roots and make a reliable, stable plant base. You should avoid moving and repotting the plant if it’s planted for less than two to three years in the same place.

But sometimes repotting becomes necessary due to various reasons. This may be due to plants overgrowing the current pot or change in the gardening location.

The best time to start repotting it is after the plant has finished flowering. If you begin the repotting during its blooming, then it hampers the growth of buds and reduces the number of flowers you may get. 

You can also split the plant when repotting to spread it out, so it has more room to grow. For the best result, use three or four canes together, so you have enough flowering canes to grow and bloom.
