What is the reason for the withering of the bottom leaves of the dragon claw flower?

Possible causes of withering of the bottom leaves of rhubarb;

1, there may be a problem with the soil quality, and excessive drainage due to adhesion is not good;

2. I may not have seen the sun for a long time;

3. It may be that too much water is poured, or the soil is too sticky and the drainage is not good. The soil in the flowerpot is always wet, which leads to the rotten roots of African claws and poor growth.

Suggestion: Use sand instead of soil and add some sawdust. It is best to soak sawdust.
