Spear saltbush: curling leaves, causes and fixes

Check these first

Look closely at the new growth for tiny insects.
Check if the soil is dry and needs a drink.
Observe if the leaves uncurl when the temperature drops.

Likely causes

Aphids
Most likely
How to tell: You will see small clusters of green or black insects on new growth. They suck the sap, which causes the leaves to twist and curl as they grow.
What to do: Spray the plant with a gentle stream of water to knock the bugs off. If they persist, apply insecticidal soap or neem oil once a week until they are gone.
Heat Stress
Possible
How to tell: The leaves curl inward during the hottest part of the day to conserve moisture. The plant usually looks better in the morning or evening.
What to do: Ensure the plant is getting enough water during extreme heat waves. While it loves full sun, providing a little afternoon shade can help during record high temperatures.

When to worry
