Pocket Botanist
Check these first
- Inspect the undersides of the leaves for small brown bumps.
- Check if the leaves stay wet for hours after watering.
- Look for soft or mushy areas around the spots.
Likely causes
Fungal Leaf Spot
PossibleHow to tell: You will see small, dark, or water soaked spots that may have a yellow halo around them. These often appear after the leaves have stayed wet for too long.
What to do: Cut away the affected leaf tissue using a sterile blade. Improve air movement around the plant with a small fan and keep the foliage dry when watering.
Scale Insects
PossibleHow to tell: These look like small, brown, raised bumps that can be scraped off with a fingernail. They often cluster along the veins or the base of the leaves.
What to do: Dab each bump with a cotton swab dipped in rubbing alcohol to kill the insect. Repeat this process every 7 days until you no longer see any new bumps.

When to worry
Worry if the spots are spreading rapidly or turning into soft, foul smelling rot. Small, dry, and stable marks are usually just cosmetic scars from past issues.
Stopping it coming back
Ensure your orchid has plenty of space for air to flow around it and always water the potting mix directly instead of the leaves.

Questions people ask
- Can I use neem oil on my Cattleya?
- Yes, but be very careful. Only apply it in the evening to avoid leaf burn and never use it when the plant is in direct sun.
- Are these spots contagious?
