What should I do if the flowers have rotten roots?

Michelia mollissima is a traditional famous flower in China, which has a long history of cultivation in China. Like its name, its flower is not big, but it looks very good-looking. Many people often keep it at home as an ornamental plant. But some friends have rotten roots in the breeding process, what should be done? Come and have a look with the editor.

1. Cut off the rotten roots

In the process of culture, when the root system of Michelia is found to be rotten, the first thing to do is to take the plant out of the pot soil, and then cut off the rotten root system to prevent the further spread of bacteria. After the root system is cleared, some plant ash is applied to the wound for disinfection, which can prevent the bacteria from secondary infection, and carbendazim or potassium permanganate can also be used, but the concentration of the agent should be paid attention to during the treatment, otherwise it will cause root poisoning and directly cause plant death.

2. Replace the matrix

Michelia root rot is mostly caused by soil discomfort, and after taking out the pot, you can give up the old soil and choose to use fermented sawdust as the cultivation substrate. It needs to be exposed to the sun before potting, so the culture medium has excellent air permeability and drainage performance, which can not only reduce the rotting roots in the later culture process, but also contribute to the recovery of root wounds.

3. Adjust moisture

Michelia does not like the environment of stagnant water, if the watering is too frequent, coupled with the poor loosening ability of the soil, a long time may cause soil consolidation, resulting in root respiration obstruction. Therefore, do not rush to water after the basin, you can spray water the next day after the basin, so that the soil can be kept dry.

4. Spraying calcium phosphate

Maintenance is also very important in the recovery process of Michelia mollissima in the later stage, and warm measures should be taken to keep the growth environment temperature about 20 degrees. At the same time, calcium phosphate solution should be sprayed every 3 days or so, which can promote rooting and make the plant recover quickly.
