Check these first
- Inspect the undersides of leaves for tiny moving insects.
- Check if the soil has dried out completely.
- Look for sticky residue on the stems.
Likely causes
Aphid infestation
Most likelyHow to tell: You will see small clusters of soft bodied insects on the undersides of leaves or near the tips of new growth. The leaves may also look slightly curled or sticky.
What to do: Spray the plant gently with a strong stream of water to knock the aphids off. If they persist, use a mild insecticidal soap spray once a week until they are gone.
Dry soil conditions
PossibleHow to tell: The soil feels dry to the touch and the plant looks stressed. Aphids often target plants that are not getting enough moisture.
What to do: Increase your watering frequency to ensure the soil stays consistently wet. Keep the pot sitting in a shallow tray of water to maintain constant moisture.

When to worry
Worry if the insects are spreading to other plants or if the Brooklime starts losing significant leaf mass. A few aphids are easily managed, but a full colony can weaken the plant quickly.
Stopping it coming back
Keep the soil consistently moist at all times, as Brooklime is much less likely to attract pests when it is healthy and well hydrated.

Questions people ask
- Will aphids kill my Brooklime?
- Usually not, but they can stunt its growth and make it look messy. It is best to wash them off as soon as you spot them.
- Can I use neem oil on Brooklime?
- Yes, but be careful to apply it in the evening to avoid burning the leaves in the sun. Water based sprays are often safer for this aquatic plant.
