How to prevent orchid root rot
Core content of this article: Introduction to orchid care knowledge, how to prevent orchid root rot, next, the site editor will introduce to netizens.
Although orchids like moisture, their fleshy roots are afraid of waterlogging. Excessive moisture or rainwater accumulation can easily cause root rot and trigger black spot disease. Therefore, the potting soil for growing orchids should not be too moist.
In winter, orchids are in a dormant or slow growth stage, and the potting soil should be slightly dry; in spring and early summer, which are important periods for orchids to root and grow leaves, the potting soil should be slightly moist; but long-term excessive moisture can also cause root rot, leading to leaf yellowing, and even death. Excess water causes soil waterlogging, poor breathability, and insufficient oxygen, hindering root respiration and causing root blackening and rot. During the plum rain or heavy rain season, pot orchids must avoid their harm, as prolonged rain and moisture make it easy for new leaves to develop black spots, and there is often a "rotten clothing" phenomenon in the flower buds, affecting flowering and appreciation. However, excessively dry potting soil can cause pseudobulbs to shrink or other tissues to lose water, affecting metabolic functions and leading to weak tissues and poor plant growth. In autumn, the potting soil should be slightly moist to benefit the following year's leaf growth and normal flowering. Therefore, orchid growers should understand the technique of "not wet in winter and not dry in autumn."
The above explains the different water requirements of orchids in different periods, so the amount of watering should be strictly controlled according to the requirements. At the same time, improper fertilization of orchids can also cause root rot, such as excessive or too concentrated fertilization, or pouring liquid fertilizer into the leaf sheath, all of which will have adverse effects on orchid growth. Fertilization should also be adjusted based on the amount of watering to promote coordinated growth.
The above [] introduces specific methods to prevent orchid root rot, hoping that everyone will like it!
