Likely causes
Overwatering
Most likelyHow to tell: The leaves feel soft or mushy, and the soil stays damp for a long time. You might notice the yellowing starting on the lower leaves first.
What to do: Stop watering immediately and let the soil dry out completely. If the soil is soggy, repot the plant into fresh, well draining succulent mix. Only water again when the pot feels very light.
Low Light
Most likelyHow to tell: The plant looks stretched out or leggy, and the leaves lose their vibrant color before turning yellow. This happens when the plant cannot produce enough energy to support its foliage.
What to do: Move your Senecio to a spot with brighter, indirect light. A south or west facing window is usually best. If you cannot provide enough natural light, consider using a grow light for 8 to 10 hours a day.

When to worry
It is normal for the oldest, bottom leaves to yellow and fall off as the plant grows. Be concerned if multiple leaves yellow at once or if the stem feels soft.
Stopping it coming back
Stick to a strict schedule of letting the soil dry out completely between waterings. Ensure your pot has plenty of drainage holes.
