Why are there spots on my Maiden pink?

It is less common for Maiden pinks to develop spots, which usually happens due to fungal issues caused by high humidity or poor air circulation. Check the leaves for fuzzy growth or discoloration to identify the issue.

Check these first

  1. Inspect the undersides of the leaves for pests or spores.
  2. Check if the leaves stay wet for long periods.
  3. Look for patterns in the spots to see if they are spreading.

Likely causes

  1. Fungal Leaf Spot

    Most likely

    How to tell: Small brown or black spots appear on the foliage, sometimes with a yellow halo. These often show up after periods of wet, rainy weather.

    What to do: Remove the affected leaves to stop the spread. Improve air circulation by spacing plants further apart or moving them to a breezier spot.

  2. Water Splashing

    Possible

    How to tell: Small, irregular spots appear after you water from above. The spots are usually just cosmetic and do not spread like a disease.

    What to do: Water at the base of the plant rather than over the leaves. Keep the foliage dry to prevent moisture from sitting on the leaves.

When to worry

Worry if the spots are spreading quickly or causing the leaves to drop. It is normal to see a few minor blemishes on older outdoor foliage.

Stopping it coming back

Water the soil directly and avoid wetting the leaves. Ensure the plant has plenty of space for air to move around it.
