How to prevent root rot in orchids? These methods are very practical
Many flower enthusiasts find orchids (detailed introduction) rather difficult to grow. In fact, orchids enjoy a humid environment, but their fleshy roots are afraid of waterlogging, so excessive moisture or rainwater accumulation easily causes root rot, leading to the appearance of many diseases. So how can orchid root rot be prevented?
Orchid (detailed introduction)
In winter, orchids are in a dormant or slow-growing stage, so the potting soil should be on the dry side; in spring and early summer, an important period for orchids to root and grow leaves, the potting soil should be on the moist side; but long-term excessive moisture also easily causes root rot, causing leaves to turn yellow and wither, and even death. This is because excess water causes waterlogging in the soil, poor aeration, and insufficient oxygen, which hinders root respiration and causes the root system to turn black and rot. During the plum rain or heavy rain season, potted orchids must be protected from the harm, because with prolonged rain and high humidity, black spots are most likely to appear on new leaves, and the flower buds often show a "rotten sheath" phenomenon, affecting flowering and ornamental value. However, if the potting soil is too dry, it easily causes the pseudobulbs to shrivel or other tissues to lose water, affecting metabolism, and also leads to weak tissues and poor plant growth. In autumn, the potting soil should be on the moist side to favor leaf growth and flowering the following year. Therefore, orchid growers should understand the trick of "not wet in winter, not dry in autumn."
The above explains the different water requirements of orchids at different stages, so the amount of watering should be strictly controlled according to these requirements. At the same time, improper fertilization of orchids also easily causes root rot; for example, too much fertilizer, too concentrated fertilizer, or pouring liquid fertilizer into the leaf sheaths will all have adverse effects on orchid growth. When fertilizing, the amount of fertilizer should also be increased or decreased according to the amount of watering, so as to coordinate growth.

Although orchids enjoy humidity, their fleshy root system is afraid of waterlogging; excessive moisture or rainwater accumulation easily causes root rot and induces black spot disease. Therefore, the potting soil for growing orchids should not normally be too wet.
