Red-veined dock · Rumex sanguineus

Why are my red-veined dock leaves curling?

It is less common for this plant to have curling leaves, but it usually happens due to aphid infestations. Check the undersides of the leaves for tiny insects to confirm this.

Check these first

  1. Inspect the undersides of the curled leaves for tiny insects.
  2. Feel the soil to see if it has dried out completely.
  3. Check if the leaves feel sticky to the touch.

Likely causes

  1. Aphids

    Most likely

    How to tell: You will see small clusters of green or black insects on the undersides of leaves or on new growth. The leaves may look distorted or sticky from honeydew.

    What to do: Spray the leaves with a strong stream of water to knock the aphids off. For a persistent problem, apply insecticidal soap or neem oil every 5 to 7 days until they are gone.

  2. Inconsistent moisture

    Possible

    How to tell: The leaves curl inward or look crispy at the edges when the soil dries out too much. The plant may also look wilted despite being in a bright spot.

    What to do: Check the soil moisture every 2 to 4 days and water whenever the surface feels dry. Keep the soil consistently damp to the touch to prevent stress.

When to worry

Curling is serious if you see insects or if the plant stops growing new leaves. It is normal for very old leaves to curl slightly as they age and die back.

Stopping it coming back

Monitor your plant regularly for pests and keep the soil consistently moist to prevent stress-related curling.

Questions people ask

Are aphids harmful to my dock?
Yes, they suck the sap from the plant and can cause stunted growth or leaf distortion. It is best to treat them as soon as you spot them.
Do I need to fertilize if my leaves curl?
No, curling is rarely caused by a lack of nutrients. Focus on pest control and proper watering first.
