Likely causes
Aphids
Most likelyHow to tell: You will see tiny green, black, or white insects huddled on the undersides of leaves or on new stems. They often leave behind a sticky substance called honeydew.
What to do: Spray the plant with a strong stream of water to knock them off. If they persist, use insecticidal soap or neem oil every 5 to 7 days until they are gone.
Spider Mites
PossibleHow to tell: Look for fine webbing between leaves and tiny yellow stippling on the foliage. These pests thrive in hot, dry conditions.
What to do: Increase humidity by misting the plant or using a pebble tray. Wipe leaves down with a damp cloth and apply horticultural oil if the population is high.

When to worry
Small numbers are manageable, but if the plant stops growing or leaves start curling, you need to act immediately. A few stray bugs are normal in an outdoor garden.
Stopping it coming back
Keep your plants healthy with consistent water and avoid over fertilizing with nitrogen, which attracts pests. Check your plants twice a week during the growing season.
