Will my leaves uncurl once I fix the problem?

Usually, the damaged leaves will stay curled or distorted. Focus on keeping the new growth healthy and green.

Can too much sun cause curling?

Yes, if the sun is too intense, the plant may curl its leaves to protect itself from moisture loss. Move it to a spot with bright, indirect light instead.

Why are my wax begonia leaves curling? Causes and fixes

Check these first

Inspect the undersides of the leaves for tiny bugs.
Feel the soil to see if it is bone dry.
Check if the plant is sitting directly in front of a heater.

Likely causes

Aphids or Mites
Most likely
How to tell: You will see tiny insects or fine webbing on the undersides of the leaves. The leaves often look distorted or puckered as the pests feed.
What to do: Spray the plant with insecticidal soap or neem oil every 5 to 7 days. Make sure to coat the undersides of the leaves thoroughly. Repeat this for 3 weeks to catch any new hatchlings.
Low Humidity
Possible
How to tell: The edges of the leaves turn crispy and curl inward while the rest of the plant looks dry. This happens most often when the air is too hot or near a heating vent.
What to do: Move the plant away from direct drafts or heaters. Place a tray filled with pebbles and water near the pot to increase local humidity. Mist the air around the plant occasionally.

When to worry

Worry if the curling is accompanied by yellowing or falling leaves, as this indicates the plant is struggling to survive. Minor curling on just one or two older leaves is usually nothing to fret about.

Stopping it coming back

Keep your plant in a spot with good air circulation and check the leaves for pests every time you water.
