- Check the soil to see if it is staying wet for too long.
- Inspect the leaves for any signs of pests like mealybugs.
- Feel the spots to see if they are soft or mushy.
Likely causes
Fungal Leaf Spot
PossibleHow to tell: You will see small, dark, or sunken spots that may have a yellow halo around them. These often appear after the plant has been exposed to prolonged damp conditions.
What to do: Immediately move the plant to a location with better air circulation and lower humidity. Trim off the most heavily affected leaves with a clean, sharp blade to stop the spread. Avoid misting the plant or getting water on the leaves during your next watering.
Sunburn
PossibleHow to tell: These spots look like bleached, dry, or reddish brown patches on the side of the plant facing the light. They appear suddenly after moving the plant to a much brighter spot.
What to do: Move the plant to a location with slightly filtered light or morning sun only. Allow it to acclimate to brighter conditions over 2 to 3 weeks. The damaged spots will not heal, but the plant will grow new, healthy leaves.

When to worry
Worry if the spots are soft, mushy, or spreading rapidly across the entire plant. Small, dry, or scarred spots are usually just cosmetic damage from past issues.
Stopping it coming back
Always water at the base of the plant rather than over the top, and ensure the soil dries out completely between waterings.

Questions people ask
- Can I wipe the spots off?
- No, these spots are usually tissue damage or fungal infections within the leaf. Wiping them will not remove the mark.
- Are these spots contagious to my other plants?
- If the spots are fungal, they can spread through water droplets or high humidity. It is best to isolate the plant until you are sure the issue is resolved.
