Why are my Salvia splendens leaves curling? Causes and fixes

Check these first

Inspect the undersides of the leaves for aphids.
Feel the top inch of soil to see if it is dry.
Observe if the leaves recover after the sun goes down.

Likely causes

Aphids
Most likely
How to tell: You will see clusters of tiny green or black insects on the new growth or undersides of leaves. 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 knock them off. If they persist, apply insecticidal soap every 5 to 7 days until they are gone.
Heat Stress
Possible
How to tell: The leaves curl inward during the hottest part of the day to conserve moisture. If they perk back up by evening, the plant is just reacting to the sun.
What to do: Move the plant to a spot with partial shade during the afternoon. Ensure you are watering every 2 to 4 days when the top inch of soil feels dry.
