I have 15 Eugenia trees planted one year ago. One has developed bumps on the stem. How do I treat this?

Would like to stop this spreading to the other trees…

Those are a type of insect known as “scale”. These are very aggressive, and develop a shell to protect it from pesticides. You will have to scrape off as many as you can and then treat with something such as neem oil, or other insecticides.
