Likely causes
Aphids
Most likelyHow to tell: You will see tiny green or black insects clustered on the undersides of leaves or along the stems. They often leave behind a sticky residue called honeydew.
What to do: Spray the plants with a steady stream of water to knock them off. If they persist, apply insecticidal soap or neem oil once a week until they are gone.
Spider Mites
PossibleHow to tell: Look for fine webbing between the leaves and tiny yellow stippling on the foliage. These pests thrive in hot and dry conditions.
What to do: Increase the humidity around your plants by misting them. Use a mild horticultural oil to treat the affected areas.
When to worry
Small numbers are manageable, but you should act if the leaves start curling or the plant stops growing. A few bugs are normal in an outdoor garden.
Stopping it coming back
Keep your clover healthy with consistent watering and full sun to help it resist infestations. Check your plants weekly during the growing season.
