How to care for Phalaenopsis orchids in a heated room in winter, and are they afraid of high temperatures?

In December, the temperature gets colder and colder. At this time, many Phalaenopsis orchids may be in a dormant state. However, some households, in order to keep them looking beautiful, start using heaters to help them along, but the result is that the leaves begin to turn yellow and dry, and the flowers gradually wither. What exactly is going on? Let's take a look together below.

For many flower lovers, orchids are the "white moonlight" in their hearts. However, because they originate from tropical rainforests, they have long enjoyed the natural conditions there of high humidity and good ventilation. So in home care, if in winter they are placed next to a particularly dry and warm heater, serious effects may appear.

The reason is that a heater will quickly cause the temperature to rise, and at this time it will also cause the humidity of the surrounding air to drop sharply. In this dry environment, the water in the leaves of Phalaenopsis orchids will quickly be drawn out, and at the same time the roots will begin to turn yellow, dry, and black. If they are placed in this kind of environment for a long time, it can even cause the plant to die outright.

So, how can you provide a suitable growing environment for Phalaenopsis orchids in winter? First, avoid placing the orchid next to a heater or anywhere else with a heat source. It is recommended to cover the plant with a black plastic bag at night to protect it from wind, then open it during the day and place it in a spot with scattered light. Second, in a relatively warm indoor space, you can improve the environment by increasing the surrounding humidity, for example by using a humidifier next to the plant, or by placing a basin full of water beside the plant. Finally, of course, you should also pay attention to maintaining ventilation to avoid pathogens breeding because the air is too enclosed.

In addition, as the temperature begins to drop in winter, Phalaenopsis orchids will also enter a dormant period. At this time, the amount of watering should be relatively reduced. It is recommended to water once every 5 to 7 days, keeping the soil slightly dry. As for fertilizing, because its own metabolism is slow, its demand for nutrients will also decrease accordingly. At this time, you must not fertilize heavily, otherwise it will cause excess nutrients, which is very unfavorable to the plant.
