Check these first

  1. Look at the shape and color of the spots.
  2. Check if you have been splashing water on the leaves.
  3. Evaluate the light levels where the plant sits.

Likely causes

  1. Fungal Leaf Spot

    Most likely

    How to tell: You will see circular brown or black spots on the leaves. These often appear when the plant stays wet for too long.

    What to do: Remove the affected leaves to stop the spread. Improve air circulation around the plant and avoid getting water on the leaves when you irrigate.

  2. Sunburn

    Possible

    How to tell: The spots look like bleached or scorched patches on the leaves. This happens if the plant is moved into direct sun too quickly.

    What to do: Move the plant to a spot with bright, indirect light. Gradually acclimate it to stronger sun over 2 to 3 weeks.

When to worry

A few spots are normal, but if they cover most of the leaf surface, the plant will struggle to photosynthesize. Take action if the spots are spreading rapidly.

Stopping it coming back

Water at the base of the plant instead of over the top. Keep the area around your Plumeria clean and well ventilated.
