Check these first

- Look at the leaves for any yellowing or mushy spots.
- Assess if the plant has been in the same light for a while.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow or mushy before falling off the stem. The soil may stay wet for too long.
What to do: Let the soil dry out until the top centimeter is dry to the touch. If the soil is waterlogged, repot the plant into fresh, well draining soil.
Low light
PossibleHow to tell: This is less common for this plant, but it happens if the begonia is kept in a dark corner for too long. The stems will stretch out and leaves will drop as the plant struggles to photosynthesize.
What to do: Move your begonia to a spot with bright indirect light. Avoid direct sun, which can burn the leaves.

When to worry
If the plant is losing many leaves at once, it is a sign of stress. Losing one or two old leaves at the base is normal as the plant grows.
Stopping it coming back
Ensure the pot has good drainage and place the plant in a spot with consistent, bright indirect light.
