What about the rotten roots of hydroponic orchids?

Flower friends who like hanging orchids always like to pinch a few branches and leaves and keep them in the water. Careful flower friends find that before long, the roots of hanging orchids begin to rot. So, what about the rotten roots of hydroponic hanging orchids?

If the root system of Cymbidium has rotted in water, it is best to clean the bottle and the root system of Cymbidium, cut off all the rotten root system, and soak and disinfect it with 500-fold solution of potassium permanganate for 20 minutes. Put the disinfected orchid in a cool place first, and then re-cultivate it with clean water for about 2 days. The environment should be semi-overcast or scattered light, and it will gradually weaken in the shade. It needs to be kept in a sunny place in winter.

If the temperature is 20-25 ℃, you need to change the water every 3 days. When the temperature is lower than 20 ℃, it is best to change the water every 5 days or so. When the temperature is higher than 25 ℃, you need to change the water once every 1-2 days. And in each change of water, flush the mucus on the roots with tap water, so that the management can ensure that it will grow well. Pay attention to do not apply fertilizer within 1 month, you can apply less in the future, which is conducive to recovery. The following are several situations and treatment methods of hydroponic hanging orchid rotten roots.

1. Low temperature

Reason:

The root of the orchid is very sensitive, especially the hydroponics, environment and water temperature are very important. When the water temperature is quite different from the room temperature, or the newly added water is too cold, the growth of the roots will be affected, which may cause rotten roots.

Solution:

Hydroponic hanging orchid rotten root is much easier, often check the growth of the root system, rotten root system should be cut off in time. Pay attention to changing water at ordinary times, make sure it is equal to room temperature, and avoid overcooling or overheating.

2. Excess nutrition

Reason:

Many people love nutrient solution when maintaining hydroponic plants. If it is used too much, it will affect the growth of Cymbidium. The content of dissolved oxygen in the nutrient solution of hydroponic culture is low, resulting in the death of plant roots due to hypoxia and gradual decay.

Solution:

Change the water frequently, clear the container wall and the root system of Cymbidium every time. The nutrient solution can be used, but be careful not to overdo it. Follow the instructions.

After the roots of Cymbidium are rotten, you can only raise them with clean water. Wait for the roots to adapt to the environment, and then add nutrient solution after growing new roots.

3. Poor water quality and high water level

Reason:

This problem of water quality should be well talked about. If there are residual plant debris or residual matrix or nutrient solution precipitation in the water, it is easy to cause rotten roots. In addition, the level of water level is also the key factor of rotten roots.

Solution:

Leave half of the orchid root in the nutrient solution, while the other half is exposed to the air. This can greatly increase the oxygen supply of plant roots and effectively reduce the occurrence of root rot.

Change the water in time to ensure that the water quality is clean. The tap water at home should be used after one day.
