Will Phalaenopsis die from high temperature and high humidity? Clever little tips for dealing with too much humidity

It is well known that growing flowers and plants depends on the weather, especially for the relatively delicate "Phalaenopsis" (moth orchid). Besides adding shade tools in summer, you also need to move it to a relatively cool spot, and it cannot be placed outside the balcony, because after hot weather comes more rain, and at this time high temperature + high humidity is the killer that has killed quite a few Phalaenopsis. So, when faced with this kind of weather, how do we care for Phalaenopsis?

Generally speaking, what Phalaenopsis dreads most is high temperature, high humidity and poor ventilation. However these three are combined, they form its "death combo", and the core thing to avoid is controlling humidity. How do you control it? The humidity at home must be kept below 60%, and you must remember this number well.

Especially for friends in the south, as soon as it rains, the humidity in the air can rise to 80%, which is considered the most ordinary thing. During this period, ventilation becomes Phalaenopsis's lifesaving straw. Besides relying on being near a window, the most direct option is of course a fan; when humidity is high, running it for a full 10 hours a day is basic practice. Take my home as an example: I put the orchid on the south balcony, and even if it is raining outside and the humidity soars to 80%, as soon as the fan starts, that stuffy feeling immediately disperses, and any crisis can be resolved. If there is good weather without rain, with humidity steady around 50%, plus a fan blowing, it is like adding wings to a tiger for Phalaenopsis, and the roots can grow steadily.

In addition, there is another key point to note: after watering, forced ventilation is a must. Even if you only watered a tiny bit, you still need to quickly turn on the small fan and blow for at least 8 hours, so the potting soil dries out faster (especially if the medium is only sphagnum moss), and the roots absolutely must not be left stuffy in dampness. Remember this sentence: orchids are not afraid of high temperature; what they fear most is humidity above 60%, and if it exceeds that, trouble is most likely to occur.

Let me share a real lesson of my own. Last year I repotted, but because I shut the Phalaenopsis in an enclosed balcony without ventilation, and then foolishly watered it, only 5 days passed before the leaves began to turn to water, feeling soft and mushy when pinched, and when I looked at the roots, they had all rotted into mush.
