Q.how to treat bumpy leaves on eugenia
Several of my new planted eugenia plants have developed bumps on the new leaves. How should I treat this? Thanks!

What do the bumps look like, how big are they and what color are they? Are they on the top-side or under-side of the leaves? Do you see any signs of an insect infestation?
There are a few possibilities. It could be eugenia psyllid.
or it could be a leaf gall:

I would need more information or a photograph for a more positive identification.
