Causes and Control methods of rotten Roots of Polygonatum odoratum

Polygonatum odoratum is a perennial herb of Liliaceae, which is native to southwest China. It has high medicinal and health value, and its leaves are green and bright, so it is a good choice as a family pot plant. In the process of breeding, many friends found that their farmed Polygonatum odoratum rotten roots, that how to solve, let's take a look at the rotten roots of Polygonatum odoratum and prevention and control methods.

Rotting root cause

There are three main causes of rotten roots of Polygonatum odoratum: diseases and insect pests, excessive fertilization and improper transplantation.

Root rot disease and insect pest is mainly a kind of disease called root rot disease. Excessive fertilization will lead to excessive soil concentration, lead to root water leakage, lead to the loss of root function, and finally lead to plant root rot death, incorrect transplanting methods, and easy to cause root damage. Causing bacterial infection.

Prevention and cure method

1. Root rot: disinfect the soil before planting, kill the bacteria in the soil, find the bacteria, use root irrigation to sterilize and rescue, and use diluted carbendazim solution to disinfect the virus. If the pathogen is found in time and the infection range is small, the infected root system can be cut off and carried out antivirus treatment, but it is found later and the infection range is larger, then it is a pity.

2. Excessive fertilization: for most plants, fertilization should be thin, keeping in mind that the fertility is too heavy, and the same is true of Polygonatum odoratum. The primary manifestation of excessive fertilization is that the leaves begin to turn yellow, and then the leaves fall and the plants wither. when the leaves begin to yellowing, we should stop fertilization, water more to dilute the soil concentration, and change the basin soil if necessary.

3. Improper transplantation: in the process of transplantation, we should be careful and patient, and ensure that the root system is not damaged in the process of transplant, the disease resistance of Polygonatum odoratum is weak, and the root damage is easy to infect pathogens, resulting in the phenomenon of rotting root. Unless necessary, the editor does not recommend transplant.

The above are the causes and prevention methods of the rotten roots of Polygonatum odoratum, which are introduced by the editor. I hope it can be helpful to you.
