Why are my Southern dewberry leaves curling?

It is less common for Southern dewberry leaves to curl, so this usually points to a pest infestation or extreme heat stress. Check the undersides of the leaves for tiny insects first.

Check these first

  1. Inspect the undersides of the curled leaves for tiny aphids.
  2. Touch the soil to see if it feels dry or hot.
  3. Observe if the leaves recover after the sun goes down.

Likely causes

  1. Aphids

    Most likely

    How to tell: You will see small, soft bodied insects clustering on the new growth or the 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 or neem oil every 5 to 7 days until they are gone.

  2. Heat Stress

    Possible

    How to tell: The leaves curl inward during the hottest part of the day when the plant loses moisture faster than it can replace it. The leaves usually look normal again by the next morning.

    What to do: Increase your watering frequency during heat waves to keep the soil consistently moist. Apply a 2 to 3 inch layer of mulch around the base to keep the roots cool.

When to worry

Worry if the leaves stay curled even at night or if you see significant yellowing. It is normal for leaves to curl slightly during peak afternoon heat in midsummer.

Stopping it coming back

Keep your dewberry well watered and monitor for pests early in the spring before populations explode.

Will curled leaves straighten out?
If the curling is caused by heat, they will often straighten out overnight. If the damage is from aphids, the affected leaf will likely stay distorted.
