Are these curled leaves going to die?

If the curling is caused by aphids, the leaves might remain distorted even after the pests are gone. The plant will eventually produce new, healthy growth.

Should I cut off the curled leaves?

You can trim off heavily damaged leaves to improve the look of the plant. Just make sure to leave enough healthy foliage for the plant to photosynthesize.

Likely causes

Aphid Infestation
Most likely
How to tell: You see small green or black insects clustering on the new growth and flower buds. The leaves look distorted or curled as the pests suck the sap.
What to do: Spray the plant with a strong stream of water to knock the aphids off. For heavier infestations, apply insecticidal soap according to the label instructions once a week.
Heat Stress
Possible
How to tell: The leaves curl inward during the hottest part of the day to conserve moisture. The plant looks wilted but recovers once the sun goes down.
What to do: Provide a bit of afternoon shade if the heat is extreme. Ensure you are watering deeply every 3 to 7 days to keep the root zone cool.

When to worry
