- Too much direct sunlight (leaf burn)
- Overwatering causing root stress
- Fungal/bacterial leaf rot
- Poor drainage or water staying in the pot
- Sudden heat exposure
What I notice from the image:
- The damaged areas are dry and burnt-looking, not soft or mushy.
- The potting soil looks quite wet/dense.
- The plant seems kept near a wall with limited airflow/light balance.
What you should do:
- Remove damaged leaves
Cut the heavily blackened leaves using clean scissors. The damaged part will not recover. - Check soil moisture
- If soil feels wet for many days, reduce watering.
- Water only when the top 1–2 inches of soil become dry.
- Improve drainage
Make sure the pot has drainage holes. Avoid water collecting at the bottom. - Avoid harsh direct afternoon sun
Keep the plant in bright indirect light for a few weeks. - Check roots if condition worsens
If stems become soft or smell bad, roots may be rotting. Repot into fresh, well-draining soil. - Fungus prevention
You can spray a mild fungicide or neem oil once weekly if black spots continue spreading.
The plant still has green healthy sections, so it can recover with proper care.
