Why are my water forget-me-not leaves curling?

It is less common for this plant to have curling leaves, and it is usually a sign of an aphid infestation. Check the undersides of the leaves for small insects.

Check these first

  1. Inspect the undersides of leaves for tiny insects.
  2. Look for white powdery spots on the foliage.
  3. Check if the leaves feel sticky to the touch.

Likely causes

  1. Aphids

    Most likely

    How to tell: You see small clusters of green or black insects on the new growth or undersides of leaves. The leaves may look distorted or curled as the pests suck the sap.

    What to do: Wash the aphids off with a gentle stream of water from a hose. If they persist, apply insecticidal soap according to the label instructions.

  2. Powdery mildew

    Possible

    How to tell: A white, dusty coating appears on the leaves, causing them to curl or twist. This is common when air circulation is poor.

    What to do: Improve air circulation by spacing plants further apart. Remove heavily infected leaves and treat the plant with a fungicide if the infection is widespread.

Questions people ask

Are aphids harmful?
