Check these first
- Check the light intensity where the plant sits.
- Observe if the yellowing is on older or newer stems.
- Test your water source or try using filtered water.
Likely causes
Too much direct sun
Most likelyHow to tell: The stems turn a pale, washed out yellow color. This happens when the plant is exposed to intense, direct sunlight for too many hours.
What to do: Keep the plant in bright light, as this species naturally grows in full sun, and keep the soil consistently moist. If the stems look scorched, a spot with some afternoon shade can help.
Water quality
PossibleHow to tell: The tips or edges of the stems turn yellow and then brown. This is often caused by high levels of chlorine or minerals in tap water.
What to do: Try using filtered or distilled water for a few weeks. This helps if your local tap water is heavily treated.

When to worry
A single yellowing stem at the base is normal as the plant grows. If the entire plant is turning yellow, it is a sign of significant stress.
