Analysis of the Uses of Phalaenopsis Leaves and the Signs of Problems
As a flower, the Phalaenopsis is undoubtedly a "dazzling star," and so in recent years it has become one of the top choices for New Year flowers in every household. However, although it is beautiful, during care it can easily bring tricky problems to new flower lovers, such as blackening, shrinking, or moldy rot on the leaves. These problems not only affect the plant's ornamental value, but may even threaten the plant's life.
In fact, the reason Phalaenopsis leaves have so many problems is that the leaves are the first place where the plant perceives disease. In other words, this is a process of dialogue between humans and the Phalaenopsis. Healthy leaves are glossy and emerald green, moderate in number, and arranged fairly symmetrically and neatly; on the contrary, conditions such as soft rot, yellowing, and drying out may appear.
If we further understand the leaf structure of the Phalaenopsis, it mainly contains obvious spongy tissue, and this tissue serves the function of regulating water for the plant, and in emergencies it can resist a dry environment. At the same time, when placed in diffused light, the leaves also break down photosynthesis and gases to help the orchid form energy and nutrients; and if placed in an environment with strong sunlight, the spongy tissue can reflect part of the light, thereby reducing the chance of light penetrating deep into the leaf and effectively reducing direct damage to the orchid's roots.
Regarding leaf pathology, the most troublesome is soft rot. It is a fungal infection of the leaves, and the usual cause is that a high-temperature environment makes it develop. If you really encounter this problem, and if the infection is in a relatively small area, you can cut off the diseased leaf, but remember that you must not cut only half of it, otherwise it cannot be cleaned completely. After cutting, sprinkle some dry carbendazim powder on the wound; if you do not have it, cinnamon powder or plant ash will also do, and can help the wound recover.
Finally, after handling it, put the whole Phalaenopsis back in its original position. As for watering, before the wound has recovered, do not let water splash onto the wound. And if the situation is yellowing, drying out, and so on, and the spots are increasing, it is recommended that you promptly recall the previous care conditions such as light, watering, fertilizing, and temperature, find the problem as soon as possible, and take corresponding measures to improve it.
