Today we will explain how to grow Dendrobium Nobile orchids in plant pots?
Set the grow room temperature between 65 to 85 degrees F with high humidity. Use pure clean water for watering plants. Fertilize Dendrobium Nobile orchids once a month. All these are basic care methods.
Below is the detailed explanation of every single care need of Dendrobium Nobile orchids.
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 on a sunny window.
Because in winters 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, 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. Because summer is its growing stage. Every plant in the growing phase needs more water, sunlight, and nutrients.
In summers water the Dendrobium Nobile orchids when the plant pot is about to completely dry.
You can check it by poking your finger in the potting soil. Or by lifting the pot. Because the water-filled plant container is heavier than the pot with less water or no water.
The number of water applications are depending on many factors. The temperature in the room, Airflow, and season of the year. All these directly affects the watering needs of a plant.
To water your orchid, pour enough water in the root area. So that the water comes out of the bottom hole. Then stop the water supply and leave the plant pot for 10 minutes. After that place the pot in its original place.
Then again repeat the process when the soil of the plant pot becomes dry.
This way you can save your plants from root fungal disease.
Soil and Plant Container
In its native place, Dendrobium Nobile orchids grow on other plants. They absorb everything from the air like Air plants. If you want to grow them indoors, you need to grow plants in well- aerated soil. That drains well- in case of overwatering.
Pre-fertilized orchid potting soil will be best to use for Dendrobium Nobile orchids care. The next thing you need to keep in mind is the choice of the plant pot.
The plant container that you are going to use for caring for Dendrobium Nobile orchids should have a drainage hole. There must be plenty of drainage holes in the plant pot. Also, choose the small size pot. Because this type of pot holds less soil this means it also holds less water. And give extra drainage power with excellent aeration properties.
Among many plant container materials, plastic containers are good to use. Because Nobile orchid is an ornamental plant, you should use decorative pots. They add more charm to your plant beauty.
If you have many new clay pots in your home but do not have a plastic pot. Then no need to buy a plastic pot. You can use the clay pots they have pores in them that increase the air circulation. They are equally good as plastic pots.
Maintain the humidity between 50 to 65%. This is the ideal range of air moisture for growing and caring Dendrobium Nobile orchids. Above this range, the humidity causes many bacterial diseases in Nobile orchids.
The easy way of increasing humidity is by grouping the plants. If this doesn’t work then use a humidity tray. A hygrometer is necessary to monitor the grow room humidity.
Caution: Dendrobium Nobile plants need balanced humidity. If you feel your plant is suffering from low air moisture and you want to increase it. Then before that, you need to increase the air calculation in the room. You can open an airy window or Turn ON the fan.
60 to 85 degrees F is the ideal temperature range for this plant. If the temperature drops below 60 degrees F. The plant starts suffering from many problems.
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.
Use liquid type water-soluble fertilizer once every 2 weeks in the active growing stage. To play safe use half 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.
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.
Dendrobium Nobile orchids is a root-bounding plant. It needs repotting every 2 to 3 years. Do not use too big 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 its new pot in few days.
Dendrobium Nobile orchids develop yellow leaves. If the plant develops yellow leaves after the bloom and they fall off the plant. It is a natural process no need to worry.
Old leaves of plants turn yellow before shedding. Then the plants develop new leaves in their place.
There are two main reasons for yellow leaves in Dendrobium Nobile orchids. The first is overwatering and the second is underwatering.
If the potting soil is wet and soggy and the plant has yellow leaves. Then the extra water is the possible cause of yellow leaves. In this case, you need to cut the water supply to the plant. In extreme cases, you have to use fresh soil to save your plants from dying.
On the other hand, if the underwatering is the problem, then you need to give some water to the plant. The problem will get solved in few days.
Overfertilization also causes yellow leaves in Dendrobium Nobile orchids. But they also develop brown tips. This indicates that the yellow leaves are due to the excessive use of nutrients. Stop using fertilizers and flush the soil. If possible use new potting soil.
Overwatering triggers fungal diseases in orchid plants. Whereas high humidity causes bacterial diseases. Bacterial diseases eat the leaves and fungal diseases eat the roots of the plants.
Disease like Botrytis cause black spots on plant leaves. It can only be cured by using strong fungicide spray. You can get such sprays from the local garden store or from the nearby pest control center.
If you are buying pesticide products from the pesticide store. You should tell them you need sprays for your plants not for your home. Because plant pesticide sprays are different from home pesticide sprays. Plants spray also costs less and they are not harmful to humans.
