Likely causes
Aphid infestation
Most likelyHow to tell: You will see small green, black, or pink insects clustering on the undersides of leaves and new flower buds. They often leave behind a sticky substance called honeydew.
What to do: Spray the plant with a strong stream of water from your hose to knock them off. If they persist, apply insecticidal soap or neem oil every 5 to 7 days until they are gone.
Weakened plant health
PossibleHow to tell: Plants that are stressed from low light or improper watering are more susceptible to pests. Look for yellowing or stunted growth alongside the bugs.
What to do: Ensure your sage gets at least 6 to 8 hours of direct sun daily. Adjust your watering schedule to ensure the soil dries out between sessions.

When to worry
A few aphids are normal, but you should act if you see large colonies covering the stems. If the plant stops growing or leaves begin to curl, it is time to treat immediately.
Stopping it coming back
Keep your sage healthy with plenty of sun and avoid overfertilizing, as excess nitrogen attracts aphids.

Questions people ask
- Will aphids kill my Baby sage?
- They rarely kill a healthy plant, but they can weaken it and spread viruses. It is best to wash them off as soon as you spot them.
- Can I use dish soap to kill them?
- A mild, non-degreasing soap mixed with water can work, but commercial insecticidal soap is safer for the plant. Avoid using soaps with heavy fragrances or degreasers.
