Turk's cap · Malvaviscus arboreus

Why are there spots on my Turk's cap leaves?

It is less common for this plant to develop spots, but it usually happens due to fungal issues caused by high humidity or poor air circulation. Check the undersides of the leaves for pests first.

Check these first

  1. Check the undersides of leaves for whiteflies.
  2. Inspect the leaves for fungal patterns.
  3. Ensure the plant has good airflow.

Likely causes

  1. Fungal leaf spot

    Most likely

    How to tell: You will see small brown or black spots with yellow halos on the foliage.

    What to do: Remove the affected leaves to stop the spread. Improve air circulation around the plant and avoid getting water on the leaves when you water.

  2. Whitefly damage

    Possible

When to worry

A few spots are manageable, but if they cover most of the leaves, the plant will struggle to photosynthesize. It is normal to see some minor wear on older leaves.

Stopping it coming back

Water at the base of the plant instead of overhead to keep the foliage dry.
