Why are my salmonberry leaves curling?

It is less common for salmonberry leaves to curl, and this usually happens when aphids are feeding on the soft new growth. Check the undersides of the curled leaves for tiny insects first.

Check these first

  1. Inspect the undersides of the curled leaves for small insects.
  2. Check the soil moisture level to see if it feels dry.
  3. Observe if the leaves recover after the sun goes down.

Likely causes

  1. Aphid infestation

    Most likely

    How to tell: You will see clusters of tiny green or pink insects on the undersides of leaves or near the tips of new stems. 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 once a week for 3 weeks until the population is gone.

  2. 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 at night, the plant is just trying to stay cool.

    What to do: Move your salmonberry to a shadier spot if it is getting too much direct afternoon sun. Ensure you are watering every 3 to 7 days to keep the soil consistently damp.

When to worry

Be concerned if the curling is accompanied by yellowing or if the plant stops putting out new growth. It is normal for leaves to curl slightly when the plant is adjusting to a new, warmer location.

Stopping it coming back

Keep your salmonberry in a cool, shady spot and monitor the new growth regularly for early signs of pests.

Questions people ask

Will my leaves uncurl once the aphids are gone?
The leaves that are already badly curled will likely stay that way. However, the new growth should emerge flat and healthy once the pest issue is resolved.
Does my salmonberry need more water if the leaves curl?
If the soil feels dry to the touch, then yes, it needs more water. Always aim to keep the soil evenly damp but never soggy.
