Likely causes
Heat Stress
Most likelyHow to tell: The leaves look crispy and curl inward during the hottest part of the day. This often happens when the plant is in direct afternoon sun.
What to do: Move your begonia to a spot with bright, indirect light. If it is outside, provide shade during the afternoon hours. Water the plant deeply if the soil feels dry.
Underwatering
PossibleHow to tell: The entire plant looks wilted and the leaves curl as they lose turgor pressure. The soil will feel dry and pull away from the edges of the pot.
What to do: Soak the soil thoroughly until water drains from the bottom of the pot. Maintain a schedule where you water every 3 to 7 days, whenever the top inch of soil feels dry.

When to worry
If the leaves remain curled even after you water and move the plant to a cooler spot, the roots may be damaged. It is normal for older leaves to curl slightly as they age and prepare to drop.
Stopping it coming back
Keep your begonia in a consistent environment with steady moisture and protection from harsh, direct afternoon sun.

Questions people ask
- Will my curled leaves flatten out again?
- Usually, once a leaf has curled due to stress, it will not return to its original shape. Focus on keeping new growth healthy and flat.
- Does low humidity cause curling?
- Wax begonias are quite adaptable, but very dry indoor air can contribute to leaf curling. You can mist the area around the plant or use a pebble tray to increase local humidity.
