Frangipani · Plumeria

Why is my plumeria losing its leaves?

Plumeria are deciduous, so they naturally drop their leaves when the weather cools down. If it is happening during the growing season, it is likely a sign of stress from watering or pests.

Check these first

  1. Check the current outdoor temperature.
  2. Look for fine webbing on the stems or leaf undersides.
  3. Examine the soil to see if it has been bone dry for too long.

Likely causes

  1. Dormancy

    Most likely

    How to tell: The leaves turn yellow or brown and fall off as temperatures drop below 60 degrees Fahrenheit. This is a natural process as the plant prepares for winter.

    What to do: Reduce watering significantly during this time. Keep the plant in a cool, bright spot and wait for spring to resume normal care.

  2. Spider Mites

    Most likely

    How to tell: You will see tiny webbing between leaves and a stippled, dusty appearance on the foliage. These pests thrive in hot, dry conditions.

    What to do: Spray the leaves thoroughly with neem oil or insecticidal soap every 7 days. Make sure to cover the undersides of the leaves where mites hide.

When to worry

Leaf drop is normal in late autumn and winter. It is only a concern if the plant is dropping leaves while it is warm and actively growing.

Stopping it coming back

Keep the plant hydrated during the summer and monitor for pests regularly. Provide a consistent, warm environment during the growing season.

Questions people ask

Will my plumeria grow leaves back?
Yes, as long as the stem is firm and healthy, it will sprout new leaves once the weather warms up in spring.
Does underwatering cause leaf drop?
Yes, if the soil stays dry for too long, the plant will shed leaves to conserve moisture. Give it a deep soak if the soil has pulled away from the sides of the pot.
