Check these first
- Inspect the undersides of the leaves for small clusters of insects.
- Check the new growth tips for sticky residue.
- Examine the soil moisture to ensure the plant is not stressed.
Likely causes
Aphid infestation
Most likelyHow to tell: You will see clusters of tiny green or black insects on the stems and leaf undersides. They often leave behind a sticky residue called honeydew.
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 for 3 weeks until they are gone.
Environmental stress
PossibleHow to tell: Plants that are already weakened by poor light or incorrect watering are more prone to pest attacks. Look for signs of wilting or discoloration alongside the bugs.
What to do: Move your plant to a spot with bright indirect light. Ensure you are watering every 3 to 7 days when the top inch of soil is dry.

When to worry
It is time to worry if the aphids are causing the leaves to curl or if the plant stops growing entirely. A few stray bugs are normal, but a full colony needs immediate treatment.
Stopping it coming back
Keep your plant healthy with consistent watering and good air circulation to discourage pests from settling in.

Questions people ask

- Yes, neem oil is effective, but apply it in the evening to avoid leaf burn from the sun. Test it on one leaf first to ensure the plant tolerates it.
- Will these bugs spread to my other plants?
- Aphids can spread quickly if your plants are touching. Isolate your Heath bedstraw until the infestation is completely cleared.
