Likely causes
Overwatering
Most likelyHow to tell: The soil feels constantly wet or swampy, and the stems near the soil line turn mushy or dark.
What to do: Stop watering until the top inch of soil feels dry to the touch. Ensure your pot has drainage holes so excess water can escape freely.
Poor Drainage
Most likelyHow to tell: Water pools on the surface of the soil for several minutes after you water. The plant looks wilted despite the soil being wet.
What to do: Repot your fairy flax into a container with better drainage holes. Use a well draining potting mix that includes perlite or sand to improve airflow.

When to worry
If the stems are black and mushy at the base, the plant is likely too far gone to save. It is normal for the plant to wilt slightly if it has been very hot, but it should recover after watering.
Stopping it coming back
Only water when the top surface of the soil feels slightly dry to the touch. Always use a pot with drainage holes to prevent standing water.

- How often should I check the soil?
- Check the soil every 3 days to see if it needs water. Fairy flax prefers to be kept evenly moist but not waterlogged.
