Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account.

Light:
Dendrobium dixonianum needs a light level of 18000-24000 lux. Distributed light is recommended.
Temperature:
The average temperature of the day in the summer is 22-24 ° C, the night 15-16 ° C, giving a daily difference of 7-9 ° C. In spring, the average day temperature is 26-27 ° C, night 8-15 ° C, and the daily difference is 11-18 ° C. The average temperature of the winter day is 21-27 ° C, the night 5-8 ° C, and the daily difference is 15-18 ° C.
Humidity:
For most of the year, Dixon's Dendrobium needs the humidity of 75-85%, but for a period of 2-3 months at the end of winter and at the beginning of spring drops to almost 60%.
Substrate, growing media and repotting:
Dendrobium dixonianum can be grown mounted on tree-fern rootstocks or cork provided that high humidity is ensured and watering is done at least once a day in summer. When growing in pots, any loose, quickly drying ground is recommended. Repotting is best done in the spring when new roots begin to grow.
Watering:
From the end of spring until the beginning of autumn, the rainfall is moderate to heavy, but in the winter it is very dry. The cultivated plants should be constantly moist during active growth, but in autumn, when new growths reach maturity, the amount of water should be gradually reduced.
Fertilizer:
It is recommended to apply a 1/4-1/2 dose of orchid fertilizer weekly. From spring to mid-summer, you can use high-nitrogen fertilizer, followed by high-phosphorus fertilizer until the end of autumn.
Rest period:
In the period of 1-2 months at the end of winter, the plants should dry completely between waterings and stay dry longer. Occasional morning fogging between waterings will help prevent the plants from drying completely. Fertilization should be significantly reduced or eliminated until spring, when watering increases. A cool, dry rest is very important for the cultivated plants and should last until the spring appears of new increments.
