What to Do When a Banana Shrub (Michelia figo) Has Root Rot? Teach You the Correct Remedies

The banana shrub (Michelia figo) is a traditional famous flower of our country, with a long history of cultivation in China. Just like its name, its flowers do not bloom large, but they look very beautiful, and many people often keep it at home as an ornamental plant. However, some friends encounter root rot during the cultivation process. What should be done about this? Let's take a look together.

1. Cut off the rotted roots

When root rot is discovered during cultivation, the first thing to do is to take the plant out of the potting soil, then cut off the rotted roots to prevent the further spread of pathogens. After clearing away the roots, apply some plant ash to the wounds for disinfection, which can prevent secondary infection by pathogens. You can also use carbendazim or potassium permanganate, but when treating, pay attention to the concentration of the agent, otherwise it will cause root poisoning and directly cause the death of the plant.

2. Replace the growing medium

Root rot in banana shrub (Michelia figo) is mostly caused by unsuitable soil. After taking it out of the pot, you can discard the old soil and choose fermented sawdust as the growing medium. Before potting, it needs to be placed under the sun to bake, as this growing medium has excellent air permeability and drainage performance, can reduce root rot in future cultivation, and also helps the recovery of root wounds.

3. Adjust moisture

The banana shrub (Michelia figo) does not like waterlogged environments. If watering is too frequent and the soil's looseness is poor, over time it may cause soil compaction, which obstructs root respiration. Therefore, after potting, do not rush to water. You can spray clear water on the second day after potting, so that the soil remains on the drier side.

4. Spray calcium phosphate

Care during the later recovery process of the banana shrub (Michelia figo) is also very important. Warmth measures are also needed, keeping the growing environment temperature at around 20 degrees, and at the same time spraying calcium phosphate solution once about every 3 days, which can promote rooting and help the plant recover quickly.
