Put an end to the empty root technique of orchids

In the process of turning and changing the pots of orchids, people often encounter the situation that the orchid root looks clean and complete on the surface but empty inside, which is commonly called the empty root of orchid. The root cause of the empty root of orchid is caused by the loss of water in the dry environment for a long time. To put an end to the empty roots of Lan Miao must prescribe the right medicine to the case. specifically, there are two measures.

First, watering should be adequate and "half of the water" should be put an end to. Watering orchids is not only a basic skill of Yilan, but also a difficult problem to master. As the saying goes, "watering orchids for three years" shows the importance of watering. The so-called "half water" means that only the upper part of the orchid basin is watered. It refers to the moderate moisture content of the plant material in the upper half of the orchid basin, while the lower part is dry, which is the crux of the empty root of the orchid. There are two ways to put an end to this phenomenon: one is to water the orchid repeatedly several times, not to stop watering at the sight of the running water at the bottom of the orchid basin. Because some orchid plants have large particle size and large gap, as long as the orchid is watered a little, there will be water flowing out from the bottom of the orchid basin, while the internal plant material is dry, so it should be watered repeatedly several times to ensure that the plant material is fully watered and moist. The second is to use the "sitting basin" (soaking basin) method to water, that is, to put the orchid basin in the container of water, so that the surface height of the basin soil is basically the same as the height of the water surface in the container, so that the water is slowly upward and fully moisturizes the plant material from the bottom of the basin. This method of watering is the most uniform and sufficient, but it is watered as little or not as possible in summer to avoid the spread of bacteria.

Second, the plant material should be mixed evenly to ensure that the orchid plant is in full contact with the root of the orchid. The ancient spectrum says that "if a root does not touch the soil, its root is empty". Practice has proved that there is insufficient contact between the basin soil and the orchid root for a long time. The phenomenon of empty root will occur when the orchid root is suspended and lost water. Based on this, this requires Yilan people to fully adjust the plant materials when planting orchids and add them in the order of large, medium and small particles, and each additional layer of plant material should gently pat the basin wall to make full contact between the basin soil and the orchid root. After finishing the basin, the "sitting basin" (soaking basin) method is used to water thoroughly; further increase the contact surface between the orchid root and the plant material, and then be included in the daily management, if managed properly, the orchid empty root phenomenon can be effectively avoided.

Third, the plant material is impervious, causing the orchid root to rot and then the empty root. Most orchid lovers like to use pure soil to grow orchids when they first come into contact with orchids, which can not break through the concept of soil. We all know that the roots of orchids belong to aerial roots and need good ventilation to grow well. Wet environment is easy to cause rotten roots. When we use horticultural soil to plant, it is easy to consolidate and not easy to filter water. Watering is wet for several days, and for a long time this will cause the orchid root to rot and cause empty roots, so when we grow orchids, we have to use granular plants with stable characters, so that the air permeability is not easy to rot the roots, and the orchids will naturally be cultivated.
