Why do Phalaenopsis orchid buds fail to open and even shrivel after you bring them home?

There are many varieties of Phalaenopsis orchids, among which "Mantianhong, Lemon Green, and Yu Ruyi" are among the most popular favorites on the flower market. Some have petals covered in dense patterns, like a sky full of stars; some give off a light, not-too-strong fragrance; and some have petals curved like a ruyi scepter, carrying a very auspicious meaning. However, these orchids of different forms and varieties are not something everyone can grow well; they are often more delicate than ordinary Phalaenopsis orchids, and if cared for poorly, all kinds of problems easily appear.

Today let's focus on the problem of bud blast in Phalaenopsis orchids. Why does bud blast happen? Logically speaking, when a Phalaenopsis orchid has just grown flower buds, it shows it is growing well and on track to bloom, but instead they slowly shrivel, the buds stop growing and drop off, or they freeze in place and dry up.

So how do you prevent problems with the buds? First, if it is just winter when you are growing a Phalaenopsis orchid, it is best not to place it near a window, because the flower spike is the first thing to catch the draft there. When the temperature around the buds changes, the orchid acts as if it has received the signal "the environment is bad, do not bloom," and its self-protection system decides to abandon the buds and stop supplying them with nutrients, so the buds slowly blast.

There is also an unavoidable situation: when a Phalaenopsis orchid bought online first arrives home, after being transported all the way from the orchid nursery, the humidity and temperature have both changed, and it has spent several days in a dark space, which also easily causes bud blast. Second, it may be a problem of root rot; if the roots are damaged, they simply cannot supply the buds, which naturally affects the number of buds. Then there is the situation where, during consecutive rainy days or cloudy weather, light is insufficient, photosynthesis is not enough, and organic ketone compounds are redistributed, which can also lead to bud blast. Finally, you need to face the fact that pests and diseases such as red spider mites and scale insects can also stop the buds from developing.

In short, when growing Phalaenopsis orchids, you should take bud blast seriously, because it means something is affecting their survival, or that they have to give up the buds in order to preserve the stem system. This is very similar to us humans: when we encounter foreign bacteria, we get sick and feel listless all over, all so the body can store greater strength to defeat the virus.
