Likely causes
Overwatering
Most likelyHow to tell: The foliage feels soft or mushy before falling off, and the soil stays damp for more than a week. You might also notice a musty smell coming from the pot.
What to do: Stop watering immediately and let the soil dry out completely. If the soil stays wet for days, repot the plant into a fresh, well draining mix. Ensure your pot has drainage holes to let excess water escape.
Insufficient Light
PossibleHow to tell: The plant looks stretched out or thin, and leaves drop from the bottom up. It will struggle to maintain its foliage without at least six hours of direct sun.
What to do: Move your flax to a spot that gets full, direct sun for most of the day. If you are growing it indoors, a south facing window is usually the best choice. Avoid placing it in dim corners or shaded areas.

When to worry
It is normal for the plant to shed a few older leaves after being moved to a new home. You should worry if the leaf drop is sudden and involves many healthy looking leaves.
Stopping it coming back
Keep your plant in a bright, sunny spot and only water when the soil is dry to the touch. Good airflow around the foliage also helps keep the plant healthy.
