Can I use a fungicide?

You can use a mild, organic fungicide if the spots continue to spread. However, improving airflow and keeping leaves dry is usually enough to stop the issue.

Are these spots caused by bugs?

Usually not, but it is always a good idea to check the undersides of the leaves for tiny pests. If you see webbing or small insects, treat the plant with insecticidal soap.

Regal Geranium: spots, causes and fixes

Check these first

Check if you are watering the leaves directly.
Look at the placement of the plant relative to the sun.
Examine the spots to see if they are soft or dry.

Likely causes

Fungal Leaf Spot
Most likely
How to tell: Small brown or black spots appear on the leaves, sometimes with a yellow halo. This often happens when the leaves stay wet for too long.
What to do: Remove the affected leaves to prevent the spread of the fungus. Water only at the base of the plant to keep the foliage dry and improve air circulation around the pot.
Sunburn
Possible
How to tell: Bleached or scorched patches appear on the leaves that receive direct, harsh sunlight. These spots are usually dry and brittle.
What to do: Move the plant to a spot with bright, indirect light or filter the sun with a sheer curtain. Avoid placing the plant in direct afternoon sun.

When to worry

A few small spots are manageable, but if they begin to spread rapidly across the entire plant, you need to act quickly. Remove damaged foliage to keep the rest of the plant healthy.

Stopping it coming back

Always water at the soil level rather than over the top of the plant. Ensure there is plenty of space between plants to allow for good airflow.
