What are the causes of orchid rot? How do you fix it?

In the process of orchid culture, the rotten root of orchid is a headache. Without finding out the reason, it will happen repeatedly every year, so what are the reasons for the rotten root of orchid? How can I fix it?

First, what are the reasons for the rotten roots of orchids?

1. The cause of water quality

In fact, many people do not particularly understand this. In fact, orchids have stricter requirements for water quality than other plants, and the acidity and basicity of unclean water quality is not suitable for orchids. It is easy to understand that if the water quality is not clean, there will be more bacteria and even toxins, and then there will be diseases in the roots. In fact, the suitable pH value of orchids is about PH5.5-6.5. if the water quality is acidic, the absorption of three elements: nitrogen, phosphorus and potassium will be limited, while the absorption of trace elements will be blocked if the pH value is alkaline.

2. The reasons for the selection of plant materials.

When choosing the cultivation medium to meet the growth needs of the orchid root, there is a word called "porosity". The orchid root needs to absorb oxygen from the pores of the cultivation medium to breathe. At this time, if the pores are occupied by water, the root will be in a state of hypoxia and suffocation, and the root will rot if it is invaded by fungi, bacteria, etc. We need to remember a sentence here: "where there is water, there is bacteria."

3. Improper maintenance

Usually take the orchid to turn the basin treatment, or pruning and so on, accidentally hurt the bud of the orchid, will lead to the phenomenon of rotten orchid bud. When applying liquid fertilizer to the orchid, the fertilizer and water entered the bud core of the orchid and could not be discharged for a long time, resulting in the decay of the bud core of the orchid. The emergence of pests and so on will also make the orchid rotten bud.

Second, how to remedy the rotten roots of orchids?

1. Select and match the seed orchid matrix.

The seed orchid matrix should be filtered and breathable, moist but not waterlogged, dry but not dry. Not only filter water breathable, but also moisturize not waterlogging, but also have a certain degree of fertility. However, it should be noted that the materials used must be non-toxic, non-harmful bacteria, non-pollution, no parasitic eggs, otherwise it will also bring harm to the root system of orchids.

2. The water for watering orchids must be clean

Polluted water, unclean water can not be used. According to many orchid books, streams and rivers are the most suitable for orchids to grow, but most orchids live in cities and do not operate orchid gardens professionally, so it is difficult to do so. Watering orchids with tap water, the author from years of practice, the effect is also very good, if possible, put the water in the bucket for a few days, let the chlorine in the water volatilized that is even better. If the orchid is watered with spring and pond water, the acidity and basicity of the orchid should be tested with PH test paper and adjusted.

3. Keep breathable

No matter what texture of the orchid basin is used, the bottom of the basin must have appropriate holes, and it is better to have a few holes around the lower part of the basin wall. In short, it should be able to breathe and filter water. To facilitate drainage and ventilation. The placement of the orchid basin, to make the basin bottom and basin wall air circulation, if there are conditions, you can use orchid flower rack, so the effect is better. In order to raise orchids well, we need suitable temperature, humidity, light and other environment, but to create a good environment for orchids is the most important link. If we cultivate orchids well, we can cultivate ideal orchids.
