What to do if Polygonatum odoratum root rots

The main cause of root rot

There are three main reasons for root rot in Polygonatum odoratum: pests and diseases, excessive fertilization, and improper transplantation.

The pests and diseases that cause root rot of Polygonatum odoratum are mainly pathogens of the genus Fusarium, and the scientific name of this disease is root rot. Excessive fertilization will lead to excessive ion concentration in the soil (the same as pickling vegetables and brewing wine), which will cause water to seep out of the roots, loss of absorption and respiratory functions, and ultimately root rot or even death (as the saying goes, burned to death).

In addition, if the transplanting is not done correctly, the roots may be injured and root rot may easily occur.

How to prevent and treat root rot of Polygonatum odoratum

Control of pests and diseases (root rot)

For root rot, if it is discovered in time, you can use the method of root injection to sterilize and rescue, use carbendazim solution (500 times solution of 50%) for disinfection. If it has been widely infected, I'm sorry...

Apply thin fertilizer frequently

For Polygonatum, fertilization should be thin and frequent, and avoid heavy fertilizers. If excessive fertilization is applied, the first sign that appears is yellowing of leaves. At this time, you should stop fertilizing, water more to reduce the salt concentration in the soil, and replace the culture soil if necessary.

Correct transplantation

During the transplanting process, ensure that the roots are not damaged, otherwise it is easy for the Polygonatum odoratum to rot. It is not recommended to transplant Polygonatum odoratum unless necessary.
