Likely causes
Inconsistent Watering
Most likelyHow to tell: The leaves turn yellow and eventually drop off. The soil feels extremely dry or constantly soggy.
What to do: Stick to a schedule where you check the soil every 3 to 7 days. Only water when the top inch of soil is dry to the touch.
Low Light
PossibleHow to tell: The plant looks stretched out and the leaves lose their vibrant green color, turning pale yellow. It is not getting enough energy to maintain its foliage.
What to do: Move the plant to a spot with bright, indirect light or partial sun. Ensure it gets at least 6 hours of light per day for best results.

When to worry
If the yellowing is widespread and happens rapidly, it is a sign of stress. A single yellow leaf at the bottom of the plant is often just the plant shedding old growth.
Stopping it coming back
Provide consistent light and avoid letting the soil stay wet for long periods. Keep the plant in a stable environment away from cold drafts.

Questions people ask
- Does my plant need fertilizer?
- Petty Spurge is not a heavy feeder. A light application of balanced fertilizer once in the spring is usually enough.
- Can too much sun cause yellowing?
- Yes, intense direct sun can sometimes bleach the leaves. If the yellowing looks like a burn, move the plant to a spot with partial shade.
