Check these first
- Inspect the undersides of leaves for clusters of tiny insects.
- Check for sticky residue on the leaves or stems.
- Look for ants, which often farm aphids.
Likely causes
Aphid infestation
Most likelyHow to tell: You will see clusters of tiny, soft bodied insects on the tender new growth. They often leave behind a sticky residue called 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.
Weakened plant health
PossibleHow to tell: Plants that are stressed from lack of water or poor light are more susceptible to pests. The plant may look generally tired or stunted.
What to do: Ensure your plant gets full sun to partial shade and keep the soil consistently moist. A healthy plant is much better at resisting bug attacks.
When to worry
If the infestation covers the entire plant and the leaves start curling or turning yellow, you need to act immediately. A few stray bugs are normal, but a full colony will kill the plant.
Stopping it coming back
Keep your plant healthy with consistent watering and good light. You can also spray the plant with neem oil once a month as a preventative measure.

Questions people ask
- Will aphids kill my Field madder?
- Yes, if left untreated, they can drain the plant of nutrients and cause it to wither. Catching them early is key.
- Can I use dish soap to kill them?
- A very mild solution of dish soap and water can work, but be careful not to use too much as it can burn the leaves. Commercial insecticidal soap is safer for the plant.
