Likely causes
Overwatering
Most likelyHow to tell: The leaves may turn yellow or brown before falling off, and the soil stays wet for a long time.
What to do: Stop watering immediately and let the top 3 inches of soil dry out completely. Ensure your pot has drainage holes so excess water can escape. In the future, only water when the top few inches of soil feel dry.
Insufficient Light
PossibleHow to tell: The plant looks sparse and the stems become long and thin as they reach for more light.
What to do: Move your eucalyptus to a spot that receives full, direct sun for at least 6 to 8 hours a day. If you are growing it indoors, a south facing window is usually best. Avoid placing it in dark corners or rooms without direct sunlight.

When to worry
It is normal for a few old leaves to drop occasionally, but losing large amounts of foliage at once is a sign of stress. If the plant is losing leaves from the bottom up, it is likely a watering issue.
Stopping it coming back
Maintain a consistent watering schedule and ensure the plant gets plenty of direct sunlight every day.
