Check these first
- Inspect the undersides of leaves for tiny clusters of insects.
- Look for white squiggly lines on the leaf surface.
- Check for sticky residue on the stems.
Likely causes
Aphids
Most likelyHow to tell: You will see clusters of tiny green or black insects on new growth and flower buds. 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.
Leaf Miners
PossibleHow to tell: Look for winding, white or pale trails inside the leaf tissue. These are tunnels created by larvae feeding between the leaf layers.
What to do: Prune off and destroy the affected leaves immediately to stop the cycle. Keep the area around the plant clean of debris to discourage adult flies.
When to worry
A few aphids are manageable, but heavy infestations that cover the flower stalks can weaken the plant significantly. Act quickly if you see the population spreading to new growth.
Stopping it coming back
Keep your plant healthy with consistent moisture, as stressed plants attract more pests. Encourage beneficial insects like ladybugs to visit your garden.
