Dendrobium has very high requirements for growing environment, and if you want to raise it well, you have to provide it with a suitable growing environment first. If the temperature is too high or too low, it will cause it to grow badly and even appear to die. So, what is the suitable growing temperature of dendrobium?

the suitable temperature for dendrobium growth
In general, the dendrobium can be kept in the environment between 15°C-30°C to keep its normal growth, but it is generally recommended to control the ambient temperature between 20°C-25°C is the most suitable. The main reason is that when the ambient temperature is too high, especially when it is higher than 35°C, the plant will stop growing. When the ambient temperature is below 10°C, the plants tend to enter a dormant or semi-dormant state and their growth becomes very slow.
Therefore, if you still want to keep it alive in winter, it is recommended to keep the ambient temperature above 10°C. If you want to let it overwinter safely and smoothly, except for a few species that can withstand low temperature around 0°C, you usually need to let the ambient temperature not to be lower than 5°C at least, and it is best to control the ambient temperature around 15°C in winter. Because most of the dendrobium’s cold tolerance is relatively poor, the ambient temperature is too low when it is also easy to let it suffer from frost damage.
Of course, the dendrobium is also sensitive to the change of day and night temperature difference, but the proper formation of day and night temperature difference in the flowering period is also more beneficial to its buds and flowers. Usually, the diurnal temperature difference is controlled between 10°C and 15°C, which is more helpful to promote its flowering. If the temperature difference between day and night is too small, it will largely affect the formation and maturation of flower buds, resulting in poor flowering results or even non-flowering.
