Why are my Calico Plant leaves curling?

It is less common for this plant to show curling leaves, and it is almost always a sign of pest activity or extreme heat. Check the undersides of the leaves for tiny insects first.

Check these first

  1. Look closely at the undersides of the curled leaves for aphids.
  2. Check the soil moisture to see if the plant is dehydrated.
  3. Move the plant away from direct afternoon sun.

Likely causes

  1. Aphid Infestation

    Most likely

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

    What to do: Wash the leaves gently with a stream of lukewarm water to knock the bugs off. Apply neem oil or insecticidal soap once a week until the pests are gone.

  2. Heat Stress

    Possible

    How to tell: The leaves curl inward to protect themselves from intense heat or direct sun. The soil will also dry out very quickly.

    What to do: Move the plant to a location with partial shade during the hottest part of the day. Increase your watering frequency slightly to keep the roots cool.

When to worry

Curling is serious if the leaves start to turn brown or crispy at the edges. It is normal for leaves to curl slightly if the plant is reacting to a very hot afternoon.

Stopping it coming back

Inspect your plant for pests every time you water it. Keep it out of harsh, direct midday sun.

Questions people ask

Can I use dish soap to kill aphids?
Yes, but use a very mild, non-detergent soap mixed with water. Rinse the leaves thoroughly after a few hours to prevent residue buildup.
Do I need to repot if the leaves curl?
Not necessarily. Curling is usually an environmental or pest issue rather than a root problem.
