Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and the stems feel soft or mushy at the base. The soil may have a sour or swampy smell.
What to do: Stop watering immediately and let the top few inches of soil dry out. If the plant is in a pot, ensure it has drainage holes and is not sitting in a saucer of standing water.
Poor Drainage

When to worry
If the base of the stem is soft and mushy, the rot has likely reached the crown and the plant may be beyond saving. Act quickly if you see yellowing leaves and wet soil.
Stopping it coming back
Always use well-draining soil and never let the pot sit in water. Only water when the top inch of soil feels dry.

Questions people ask
- Can I save a plant with root rot?
- If you catch it early, you can save the plant by trimming the dead roots and repotting it in dry soil. If the roots are mostly black and mushy, it is usually too late.
- How often should I water to prevent rot?
- Water every 3 to 7 days, but always check the soil first. If the soil is still damp, wait another day or two before watering again.
