Check these first

  1. Check the soil to see if it is bone dry.
  2. Look for a white dusty coating on the leaves.
  3. Move the plant to a spot with better airflow.

Likely causes

  1. Severe Dehydration

    Most likely

    How to tell: The leaves wilt and then fall off the stems in large numbers.

    What to do: Soak the soil thoroughly to rehydrate the root ball. Ensure you water every 2 to 4 days to prevent this from happening again.

  2. Powdery Mildew

    Possible

    How to tell: A white dusty coating appears on the leaves before they drop off.

    What to do: Improve air circulation around the plant immediately. You can wipe leaves with a damp cloth or use a mild fungicide if the infection is heavy.

Stopping it coming back

Keep the soil damp and ensure the plant has plenty of space and airflow to prevent fungal issues.
