Are aphids harmful to the whole plant?

A small number of aphids usually won't kill a healthy willow. However, a large colony can weaken the plant and make it susceptible to other diseases.

Do I need to use chemical pesticides?

Avoid harsh chemicals if possible, as they can kill beneficial insects. Insecticidal soap or neem oil are much safer options for your willow.

Why are there tiny bugs on my eared willow? Causes and fixes

Check these first

Look closely at the tips of new branches.
Check for sticky residue on the leaves.
Wash the plant with a firm water spray.

Likely causes

Aphid Infestation
Most likely
How to tell: You will see clusters of tiny green or black insects on the undersides of leaves and on new stems. They often leave behind a sticky substance called honeydew.
What to do: Spray the aphids off with a strong stream of water from your garden hose. If they persist, apply insecticidal soap directly to the pests every 5 to 7 days.
Ant Activity
Possible
How to tell: You notice ants crawling up and down the stems of your willow. They are likely farming the aphids for their honeydew.
What to do: Focus on removing the aphids first, as the ants will leave once their food source is gone. You can also place a sticky barrier around the base of the trunk to stop ants from climbing.

When to worry

Take action as soon as you see them, as they multiply very quickly. If the plant looks stunted or the leaves are curling severely, the infestation is heavy.

Stopping it coming back

Encourage beneficial insects like ladybugs to visit your garden, as they are natural predators of aphids. Keep the plant healthy with consistent watering.
