What to do if a banana shrub (Michelia figo) has root rot? The latest solution
The banana shrub (Michelia figo) is a traditional famous flower of our country, with a long history of cultivation in our country. 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? Come take a look with the editor.
1. Prune away the rotted roots
When root rot is found in the banana shrub during cultivation, the first thing to do is take the plant out of the potting soil, then prune away the rotted roots to prevent the further spread of pathogens. After clearing the roots, apply some plant ash to the wounds for disinfection. This can prevent secondary infection by pathogens. Carbendazim or potassium permanganate can also be used, but when treating, pay attention to the concentration of the agent, otherwise it will cause root poisoning and directly cause the plant to die.
2. Replace the growing medium
Root rot in the banana shrub is mostly caused by unsuitable soil. After removing it from the pot, the old soil can be discarded, and fermented sawdust can be chosen as the growing medium. Before potting, it needs to be placed under the sun to bake. This growing medium has excellent air permeability and drainage performance, can reduce root rot in future cultivation, and also helps the root wounds recover.
3. Adjust moisture
The banana shrub does not like waterlogged environments. If watering is too frequent, and the soil's loosening ability is poor, over time the soil may become compacted, causing the roots' breathing to be blocked. So after potting, do not rush to water. On the second day after potting, spray clean water so that the soil remains on the drier side.
4. Spray calcium phosphate
Care during the later recovery process of the banana shrub 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. This can promote rooting and help the plant recover quickly.
