Check these first
- Check the soil moisture by sticking your finger 2 inches deep into the ground.
- Inspect the base of the plant for any signs of mushy stems or dark discoloration.
- Verify that the area around the plant does not collect standing water after rain.
Likely causes
Poor soil drainage
Most likelyHow to tell: The soil feels heavy and wet for days after watering, and the leaves may start to yellow or wilt despite the dampness. You might notice a sour or swampy smell coming from the base of the plant.
What to do: Amend your soil with organic matter like compost to improve drainage. If the plant is in a container, ensure it has large drainage holes at the bottom. Avoid watering until the top 2 inches of soil feel dry to the touch.
Overwatering
PossibleHow to tell: The foliage turns yellow and drops prematurely while the stems feel soft or mushy. This often occurs if you water on a strict schedule regardless of how dry the soil actually is.
What to do: Adjust your watering routine to match the current weather conditions. Only water when the top 2 inches of soil are dry. During rainy or cool periods, skip watering entirely until the soil dries out.

When to worry
It is serious if the leaves are wilting and the stems feel soft, as this indicates the rot has spread to the crown. If the plant is just dropping a few older leaves after a heavy rain, it is likely just adjusting to the moisture.
Stopping it coming back
Ensure your mock orange is planted in well draining soil and avoid watering if the ground is already saturated.

Questions people ask
- Can I save a mock orange with root rot?
- If the rot is caught early, you can save it by improving drainage and reducing water. If the roots are black and mushy, the plant may be too far gone to recover.
- Does mulch cause root rot?
- Mulch is helpful for moisture retention, but piling it directly against the stems can trap too much water. Keep the mulch a few inches away from the base of the plant to allow for airflow.
