What to do if the roots of Dendrobium rot

Causes of Dendrobium root rot:

Improper substrate selection

The substrate for growing Dendrobium is not suitable. Generally, during the growth process, Dendrobium has strict requirements on the substrate, which requires good air permeability. If the air permeability of the substrate for growing Dendrobium is too poor, it is easy to cause the roots of Dendrobium to rot.

Disease attack

Due to the harm of pathogens, Dendrobium is very easy to be infected when it is cultivated on a large scale. Root infection with pathogens is also one of the main causes of root rot of Dendrobium.

Improper management of fertilizer and water

During the cultivation process of Dendrobium, excessive watering and other situations may occur. If too much watering or fertilization occurs, it will cause serious root rot of Dendrobium.

Treatment methods for root rot of Dendrobium

Ventilation and humidity control to reduce root rot

There may be many reasons for the root rot of Dendrobium. You can soak the plants in fungicides such as streptomycin, then replace them with new substrates and replant them. It is necessary to control the humidity of the substrate and pay attention to more ventilation to reduce root rot.

Improve the maintenance environment

Dendrobium likes a warm and humid environment, and the humidity of the environment where it grows should be above 80% . It will grow poorly in an environment where the light is too strong or too weak, the temperature is too high or too low, the soil is poor or the water retention capacity is poor.

Disinfection in time

Cut off rotten roots and disinfect the cut ends promptly. In daily maintenance, pay attention to increasing the environmental humidity and apply less fertilizer. It must be raised in a semi-shaded environment, avoid direct sunlight, and keep the temperature as low as possible.
