Shiny bush · Peperomia pellucida

Why does my Peperomia pellucida have spots on its leaves?

It is less common for this plant to develop spots, which usually points to fungal issues from poor airflow or water sitting on the foliage. Check the underside of the leaves first to rule out pests.

Check these first

  1. Inspect the undersides of the leaves for white fuzzy insects.
  2. Check if the leaves are staying wet after you water.
  3. Ensure the plant has enough space for air to circulate.

Likely causes

  1. Fungal Leaf Spot

    Possible

    How to tell: Small brown or black spots appear on the leaves, sometimes with a yellow halo. This happens when the leaves stay wet for too long after watering.

    What to do: Remove the affected leaves immediately to stop the spread. Improve airflow around the plant and always water at the soil level instead of over the leaves.

  2. Mealybugs

    Possible

    How to tell: You will see small white cottony masses in the leaf axils or on the undersides of leaves. These pests suck sap and leave behind sticky residue that can cause spots.

    What to do: Dab the insects with a cotton swab dipped in rubbing alcohol. For larger infestations, spray the plant with insecticidal soap every 7 days until they are gone.

When to worry

Worry if the spots are spreading quickly or if the leaves are dropping off. A few tiny marks on an older leaf are usually nothing to stress about.

Stopping it coming back

Water only the soil and keep the foliage dry. Provide good ventilation to prevent moisture from lingering on the leaves.
