How is the orchid root thin and yellow?

The normal root of an orchid is the growing point, that is, the tip of the root is white, and the closer it is to the gourd, the more yellow it is. The stronger and longer the roots are, the healthier the orchids grow. The roots of orchids are thin and yellow, mainly due to lack of nutrition and thin growth. Emaciated orchids encounter adverse conditions, which will cause pathological changes.

Like crops, orchids can be divided into vegetative growth stage and reproductive growth stage. When growing roots and leaves, orchids belong to the vegetative growth stage, and the nutrition needed is nitrogen fertilizer; in the growth stage, the lack of nitrogen fertilizer leads to the poor growth of orchids, especially the underdeveloped root system, resulting in thin and thin roots, forming thin and weak roots. therefore, even the growth point grows slowly and the color turns yellow. When the orchid is short of nitrogen fertilizer, the leaves will lose green and turn yellow, especially the leaves at the bottom of the periphery become more yellow, or even yellow and withered too early. The solution is that in the whole process of orchid culture, the orchid uses organic fertilizer as the main fertilizer, such as fermented rotten and ripe chicken manure, sheep manure and cake fertilizer, which has long fertilizer effect, rich and complete nutrition, and can adapt to any growth stage. so as to quickly solve the problem of orchid thin due to lack of fertilizer.

In short, the orchid root is thin and small, and yellowing, which is a sign of lack of nutrition. This problem can be solved by applying sufficient organic fertilizer.
