Orchids that have been raised for many years have never rotted their roots. How did you do that? Orchids need roots, and only thick and full roots can give birth to strong orchids. I firmly believe that all orchid growers know this truth. So everyone puts how to raise orchids in the first place. Therefore, before planting orchids, we should learn and train the preparation of various plant materials. In addition to planting materials will affect the root system of orchids, another important thing is probably water. The water is in direct contact with the orchid root outside the plant material. Because of this, many orchid growers attribute the root rot of orchids to water. This makes the water take the blame, and the objective fact is really not like this.

Orchids rot, which I didn't notice before. Because I have raised orchids in this era, I have encountered all kinds of diseases and insect pests, both common and uncommon. But only I have never encountered root rot. Then, why do orchids rot during the peak period of growth and development in spring and summer? You Lan used to tell me that the roots of orchids are likely to rot because of excessive watering.

First, don't dare to water. Although orchids have good drought tolerance, even if they are watered less, their survival will not be affected. However, at the peak of growth and development in spring and summer, orchid roots grow rapidly, and a large amount of waste gas is generated after basic metabolism, and usually a part of waste gas will accumulate in plant materials of flowerpots.

One purpose of orchid watering is to clean the waste gas in flowerpot planting materials, which can clean the pot soil environment. If you don't dare to water for a long time (orchids that rain outdoors basically don't have this problem), the natural environment of the basin soil will deteriorate, which will lead to orchid root rot.

Second, I dare not sharpen my own seedlings. Summer is coming, and the climate is getting hot. Some orchid growers like to put orchids in a comfortable environment and dare not let them bask in the sun or blow hot air. A comfortable environment can generally be achieved by giving up natural ventilation. In this way, the inhalation range of orchid leaves will be greatly reduced; At the same time, the photosynthesis of plants gradually weakened.

In this environment, the communication between orchid leaves and roots is unstable and inactive. As the saying goes: pain makes no sense, and details don't hurt. The interaction and communication in orchid plants are not smooth, and the orchid roots in soil are easy to suffocate, leading to root rot.

3. It is also beyond reproach and necessary for orchids at the peak of growth and development to apply fertilizer reasonably and moderately to promote the growth and development of orchid seedlings. But there are many points to master in orchid fertilization. In the past papers and videos, there are also many cases of orchid root rot and seedling rot caused by unreasonable fertilization.

The roots of orchids are very sensitive to chemical fertilizers. If the concentration of fertilizer and water is not well mastered, once the new roots of orchids come into contact, it will definitely lead to root rot. When the new roots rot, it will pollute the basin soil, and even the old roots with good resistance can't bear this natural environment. The conclusion is that the root of the whole orchid is rotten.
