Why are my habanero pepper leaves curling? Causes and fixes

Check these first

Inspect the undersides of leaves for aphids.
Feel the soil to see if it is dry.
Check if the leaves recover when the sun goes down.

Likely causes

Aphids
Most likely
How to tell: You will see small green or black insects clustering on the undersides of leaves and new growth. They cause leaves to twist and curl as they feed on sap.
What to do: Spray the plant with a strong stream of water to knock them off. Follow up with insecticidal soap applied every 5 to 7 days until the pests are gone.
Heat Stress
Most likely
How to tell: Leaves curl inward during the hottest part of the day to conserve moisture. If they flatten out at night, the plant is just trying to stay cool.
What to do: Provide afternoon shade if temperatures exceed 90 degrees. Ensure you water deeply every 2 to 4 days so the roots stay hydrated.
