1、 How to save

1. Rotten root analysis

Watering too much will cause its roots to rot. The amount of water poured should be reduced. Wait until the soil dries out before watering. The soil must not hold water. In addition, if the weather gets cold and the temperature drops, the root and stem are frostbitten, it can't be saved. Generally, it cannot survive normally when the temperature is below 5 ℃

2. Rotten roots were removed and disinfected

If only the root decays, its root can be cut off and soaked in special disinfectant. It can take root again by planting in new soil. If the trunk part of the plant decays, the chance of saving is relatively small. Once the tissue inside the trunk becomes soft and ponding occurs, there is no way to save it

3. Incision treatment

Use a special disinfection knife to cut off the rotten root part, and after disinfection, in order to avoid infection, you can apply plant ash on the cutting part. Then put it in a cool and ventilated place to dry for 2 hours

4. Upper basin curing

After the rotten roots are treated, they can be well cared for and put into the pot. After changing the new basin, the soil should also be disinfected or special nutrient soil should be used. Be careful not to block the small hole at the bottom of the flowerpot. Ensure the air permeability of the basin bottom. Do a good job of later maintenance and keep the temperature at about 15 ℃

2、 What about serious rotten roots

Its roots can be trimmed with scissors. Cut off all the rotten roots. Let it take root again. If its stem also has rotten parts, it needs to be cleaned. Soak in disinfectant solution for one day and one night. Place it in a cool and ventilated place to dry, and you can replant it
