Likely causes
Overwatering
Most likelyHow to tell: The lower leaves turn yellow and drop while the soil remains soggy for days.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. Ensure your pot has drainage holes and consider repotting into a faster draining mix if the soil stays wet.
Light deficiency
PossibleHow to tell: The plant looks stretched out and drops leaves from the bottom up as it struggles to photosynthesize.
What to do: Move your tarragon to a spot with at least 6 to 8 hours of direct sun. If you are growing indoors, place it in a south facing window or use a grow light.

When to worry
If the plant drops all its foliage within a few days, it is likely in severe distress. It is normal for a few older leaves to drop occasionally as the plant grows.
Stopping it coming back
Maintain a consistent watering schedule and ensure the plant gets plenty of direct sunlight every day.
