Likely causes
Environmental shock
Most likelyHow to tell: Leaves fall off shortly after you move the plant to a new spot with different light or temperature. The plant otherwise looks healthy.
What to do: Keep the plant in a stable environment with consistent light and temperature. It will likely stop dropping leaves once it adjusts to the new spot over a few weeks.
Oleander leaf scorch
PossibleHow to tell: Leaves turn brown and die back from the tips before falling off. This bacterial infection often spreads across the entire plant.
What to do: Prune away the affected branches to stop the spread of the bacteria. Disinfect your pruning shears with alcohol between every cut to avoid contaminating healthy parts of the plant.

When to worry
If the leaves are falling rapidly or showing brown, scorched tips, it is serious. It is normal for an oleander to shed a few old, inner leaves as it grows.
Stopping it coming back
Avoid moving your plant frequently and keep it in a stable, sunny location.
