Are aphids harmful to the whole plant?

They weaken the plant by draining sap and can spread viruses. While a few are fine, a large colony needs to be managed.

Do I need to use harsh chemicals?

No, avoid harsh pesticides as they kill the good bugs that eat the aphids. Water and insecticidal soap are usually enough.

Likely causes

Aphids
Most likely
How to tell: You will see clusters of tiny green or pink insects on new shoots and buds. They often leave behind a sticky substance called honeydew.
What to do: Blast the aphids off with a strong stream of water from your garden hose. If they return, apply insecticidal soap every 5 to 7 days until they are gone.
Rose Gall Wasps
Possible
How to tell: You will notice strange, mossy, or woody growths on the stems or leaves. These are homes for wasp larvae.
What to do: Prune out the galls during the winter or early spring before the wasps emerge. Dispose of the cut material in the trash.

When to worry

Small numbers of aphids are normal and usually managed by ladybugs. Worry if the growth is severely distorted or if the plant stops producing flowers.

Stopping it coming back

Encourage beneficial insects like ladybugs and lacewings to visit your garden by planting diverse flowers nearby. Avoid heavy nitrogen fertilizers that create soft, succulent growth that aphids love.
