Will my leaves uncurl once I fix the problem?

If the curling was caused by heat, the leaves will often flatten out again once the plant is hydrated. If the damage was caused by aphids, those specific leaves may remain slightly distorted.

Can I use neem oil for the aphids?

Yes, neem oil is effective against aphids. Apply it in the evening to avoid burning the leaves in the direct sun.

Likely causes

Aphid infestation
Most likely
How to tell: You will see small green or black insects clustering on the undersides of leaves or on new growth. The leaves may look distorted or sticky from the honeydew they leave behind.
What to do: Spray the plant with a strong stream of water to dislodge the bugs. If they persist, apply insecticidal soap once a week until they are gone.
Heat stress
Possible
How to tell: The leaves curl inward during the hottest part of the day when the plant loses moisture faster than it can replace it. The plant usually perks back up once the sun goes down.
What to do: Increase your watering frequency during heat waves to keep the soil evenly moist. Consider providing a light shade cloth during the peak afternoon sun if temperatures stay above 90 degrees.

When to worry

Worry if the leaves stay curled even at night or if you see visible damage to the plant tissue. It is normal for leaves to curl slightly during intense afternoon heat as a defensive measure.

Stopping it coming back

Keep your plant well watered during dry spells and check for pests every time you water. Healthy, well hydrated plants are much less attractive to aphids.
