Likely causes
Poor Drainage
Most likelyHow to tell: The leaves turn yellow and wilt even when the soil is wet. The base of the stem may look mushy or discolored.
What to do: Gently lift the plant and inspect the roots. Trim away any black, slimy roots with clean scissors and repot into fresh, sandy, well draining soil.
Overwatering
PossibleHow to tell: The soil surface stays damp for more than 7 days. The plant looks generally unhappy and stops growing.
What to do: Wait until the top inch of soil is completely dry before watering again. Ensure your pot has large drainage holes at the bottom.

When to worry
If the stem base is soft and mushy, the rot has likely spread too far to save the plant. It is normal for the lowest, oldest leaves to yellow and drop as the plant matures.
Stopping it coming back
Always use a gritty, fast draining soil mix and never let the pot sit in a saucer of standing water.

Questions people ask
- Can I save a poppy with root rot?
- If the rot is caught early and the roots are not all black, you can trim the bad parts and repot. If the stem is mushy, the plant is usually too far gone.
- How often should I water to prevent this?
- Water every 3 to 7 days, but only when the top inch of soil feels dry. Never water on a strict schedule if the soil is still damp.
