Check these first

  1. Look closely at the undersides of the leaves.

  3. Examine the plant for white powdery patches.

Likely causes

  1. Aphids

    Most likely

    How to tell: You see tiny green or black insects clustering on new growth and flower buds.

    What to do: Spray the plant with a gentle stream of water to knock them off. If they persist, apply insecticidal soap once a week until they are gone.

  2. Powdery Mildew

    Possible

    How to tell: A white, dusty fungal growth appears on the leaves during humid weather.

    What to do: Improve air circulation around the plant by spacing it away from others. Remove heavily affected leaves and treat the rest with a neem oil spray.

When to worry

Small numbers of insects are usually manageable, but you should act if you see significant leaf distortion or yellowing. Treat immediately if you spot powdery mildew to prevent it from spreading.

Stopping it coming back

Keep the plant healthy with proper watering and ensure it has plenty of space for air to move around the leaves.

Questions people ask

Can I use household soap to kill pests?
Avoid using harsh dish soaps, which can damage the leaves. Use a dedicated insecticidal soap or a mild horticultural soap.
Why does my plant have white dust on it?
That is likely powdery mildew, which thrives in high humidity and poor airflow. Increase ventilation and keep the foliage dry when watering.
