Will my leaves uncurl after I remove the aphids?

The leaves that are already badly curled will likely stay that way. However, the new growth should emerge healthy once the pest population is under control.

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 sun.

Why are my Abelia leaves curling? Causes and fixes

Check these first

Inspect the undersides of the curling leaves for small insects.
Check the soil moisture to see if the plant is dehydrated.
Look for sticky residue on the leaves.

Likely causes

Aphids
Most likely
How to tell: You will see clusters of tiny green or black insects on the new stems and the undersides of leaves. The leaves often look distorted or sticky from the honeydew they leave behind.
What to do: Spray the plant with a strong stream of water to knock the aphids off. If they persist, apply insecticidal soap directly to the affected areas every 5 to 7 days until they are gone.
Heat Stress
Possible
How to tell: This is less common for this plant, and usually happens when the soil dries out completely during a heatwave. The leaves will curl inward to conserve moisture.
What to do: Move your plant to a spot with partial shade during the hottest part of the day. Ensure you water deeply every 7 to 14 days when the top inch of soil feels dry.
