Check these first
- Inspect the undersides of the leaves for small insects.
- Look for a white powdery substance on the leaf surfaces.
- Check if the new growth is curled or stunted.
Likely causes
Aphids
Most likelyHow to tell: You will see tiny green or black insects clustered on the tender new growth. They often cause the leaves to curl or look distorted.
What to do: Spray the plant with a strong stream of water from your garden hose to knock them off. If they persist, apply insecticidal soap once a week until the infestation clears.
Powdery mildew
Most likelyHow to tell: This fungal issue shows up as a white, dusty coating on the surface of the leaves. It thrives when the air is humid and airflow is poor.
What to do: Prune out the most affected branches to improve air circulation around the center of the shrub. Apply a neem oil spray in the early morning to help stop the spread.
