Pocket Botanist
Check these first

- Examine the soil surface for signs of mold or fungus.
Likely causes
Fungal Leaf Spot
PossibleHow to tell: Small brown or black spots appear on the blades often with a yellow halo.
What to do: Remove the affected blades to stop the spread. Improve air circulation around the plant by thinning out the clump or moving it to a breezier spot.
Crown Rot
PossibleHow to tell: Dark spots appear at the base of the plant where the leaves meet the soil.
What to do: Cut away the rotted sections and ensure the crown is not buried too deep in the soil. Keep the base dry by watering the soil directly rather than overhead.

When to worry
Worry if the spots spread rapidly or if the center of the plant begins to collapse. Minor spotting on a few blades is usually manageable with better airflow.
Stopping it coming back
Water at the base of the plant and avoid getting the foliage wet. Give the plant plenty of space to ensure good air movement.

Questions people ask
- Is leaf spot contagious to other plants?

- Do I need to use a fungicide?
- Usually, improving airflow and keeping the foliage dry is enough. Fungicides are rarely needed if you manage the environment correctly.
