Likely causes
Aphid Infestation
Most likelyHow to tell: You will see small, soft bodied insects clustering on the undersides of leaves or on new shoots. The leaves may appear curled, distorted, or sticky from honeydew.
What to do: Spray the affected areas with a strong stream of water to knock the aphids off. If the infestation is heavy, apply insecticidal soap according to the label instructions.
Water Stress
PossibleHow to tell: Leaves curl inward or droop during hot, dry periods when the plant is not getting enough moisture. The soil will feel dry several inches down.
What to do: Water the plant deeply every 7 to 14 days during dry summer months. Ensure the water reaches the root zone to help the plant recover its turgor pressure.

When to worry
Worry if the curling is accompanied by yellowing or if the infestation covers the entire plant. Minor curling on a few leaves is usually not a threat to the plant's health.
Stopping it coming back
Monitor new spring growth for aphids and keep the plant well hydrated during the heat of summer to prevent stress.
