Check these first
- Feel the soil to see if it is soggy.
- Check if the plant is sitting in direct sunlight.
- Inspect the drainage holes to ensure they are not blocked.
Likely causes
Overwatering
Most likelyHow to tell: The foliage feels mushy and the soil stays wet for more than a week. You might notice a sour smell coming from the pot.
What to do: Stop watering until the top inch of soil feels dry to the touch. Ensure your pot has drainage holes so extra water can escape freely.
Sunburn
PossibleHow to tell: Yellowing happens mostly on the side of the plant facing the light source. The leaves might look bleached or crispy rather than soft.
What to do: Move your plant to a spot with bright, indirect light or partial shade. Keep it away from harsh afternoon sunbeams that hit the foliage directly.

When to worry
Worry if the yellowing spreads rapidly across the whole plant. It is normal for the oldest, lowest stems to turn yellow and die back occasionally.
Stopping it coming back
Keep the soil consistently damp but never waterlogged by checking moisture every 3 to 7 days. Provide consistent, filtered light to keep the foliage healthy.
