Likely causes
Fungal Infection
Most likelyHow to tell: Small, dark, or brown spots appear on the leaves, sometimes with a yellow halo. These spots may grow larger if the air stays humid.
What to do: Remove the affected leaves to stop the spread. Improve airflow around the plant and move it to a spot with lower humidity.
Water on Foliage
PossibleHow to tell: Spots appear after you have misted the plant or splashed water on the leaves during watering.
What to do: Stop misting your yucca entirely. Always water the soil directly and keep the leaves dry.

When to worry
If the spots are spreading rapidly across the entire plant, you need to act fast. A few small spots are usually manageable with better care.
Stopping it coming back
Keep the foliage dry and ensure the plant is in a location with good air circulation. Avoid high humidity environments.

Questions people ask
- Should I mist my yucca?
- No, yuccas prefer dry air and do not need misting. Misting can lead to fungal spots and leaf damage.
- Are these spots pests?
- Usually not, but check the undersides of the leaves for tiny bugs just in case. If the spots are dark and sunken, it is likely fungal.
