- Inspect the undersides of leaves for tiny insects.
- Check for sticky residue on the foliage.

Likely causes
Aphid infestation
Most likelyHow to tell: You will see clusters of tiny green or black insects on stems and leaf undersides. Leaves may look distorted or sticky from honeydew.
What to do: Spray the plant with a strong stream of water to knock them off. If they persist, apply insecticidal soap every 5 to 7 days until they are gone.
Poor air circulation
PossibleHow to tell: Stagnant air around the plant makes it easier for pests to settle in and multiply. The plant looks crowded and lacks airflow.
What to do: Prune back nearby plants to improve airflow. Ensure your Meadowsweet has enough space to breathe in its garden spot.
