- Assess the light levels to confirm the plant is getting full sun.
- Inspect the stems for any signs of rot or decay.
Likely causes
Soggy soil
Most likelyHow to tell: Leaves turn yellow or brown before falling off, often starting from the bottom of the stems. The soil feels heavy and wet for days after watering.
What to do: Stop watering immediately and move the plant to a brighter, warmer spot to help the soil dry out. If the soil remains wet, repot into a mix designed for succulents or alpine plants.
Lack of sunlight
PossibleHow to tell: The plant becomes leggy and drops leaves because it cannot produce enough energy in low light. This plant requires full, direct sun to stay healthy.
What to do: Move the plant to a location where it receives at least 6 to 8 hours of direct sunlight daily. Gradually introduce it to more light over a week to avoid leaf burn.

Questions people ask
- Does this plant go dormant?
- Yes, it may lose some leaves as it enters dormancy in late autumn or winter. This is a natural process and not a cause for concern.
- Will the leaves grow back?
- Once a stem is bare, it rarely grows new leaves in that exact spot. You can prune back long, bare stems in spring to encourage fresh, bushy growth.
