Should I cut off all the spotted leaves?

Yes, it is best to trim off heavily spotted leaves to prevent the fungus from spreading. Use clean, sharp scissors and wipe the blades with alcohol between cuts.

Can I use a fungicide on my plant?

You can use a copper based fungicide if the spots continue to spread after you have improved airflow. Always follow the label instructions carefully.

St. Bernard's lily: spots, causes and fixes

Check these first

Inspect the leaves for fuzzy growth or dark rings.
Feel the top inch of soil to see if it is soggy.
Check if the plant is crowded by other pots.

Likely causes

Fungal leaf spot
Possible
How to tell: You will see small brown or black circular spots that may have a yellow halo around them. These often appear after the foliage has stayed wet for too long.
What to do: Remove the affected leaves immediately to stop the spread. Improve airflow around the plant and always water at the base rather than over the leaves.
Overwatering
Possible
How to tell: The spots may look water soaked or mushy, often accompanied by yellowing leaf edges. This happens when the roots cannot breathe in soggy soil.
What to do: Let the top inch of soil dry out completely before watering again. Ensure your pot has drainage holes so excess water can escape.

When to worry

Worry if the spots are spreading rapidly to new growth or if the stems start to collapse. A few older leaves with minor blemishes are usually not a cause for alarm.

Stopping it coming back

Water only at the soil level and keep the leaves dry. Ensure the plant has enough space for air to move freely around it.
